Recommended: Guido Van Rossum influence on python language
History of Python: “Python is an experiment in how much freedom programmers need. Too much freedom and nobody can read another's code; too little, and expressiveness is endangered.” These were the words of Guido Van Rossum ( the Creator of Python) when The idea of Python was conceived in the 1980s of the 20th century and brought to life in the 90s. Guido Van Rossum was wanting to make a change in the way computer programming was at the time, Naming the Program after Monty Python, a comedy group that performed in the late 1960s and early 70s. Today, Python is a very widely known computer programming language that shares similarities with some of the more earlier models of computer programs, Python was designed to be easy to understand and can …show more content…
However, Python has its ways of showing these newcomers or experienced users a path to guide them correctly using many types of errors in which the program holds instock, these errors are known as the syntax, run-time, and logical errors. In Python, a Syntax error is a used to detect mistakes in the program, and terminate the programs execution until resolved. Some common Syntax error examples are typographical errors like mismatched parentheses or string quotes or faulty indentation etc.. and like syntax errors, The run time error is a bit harder to detect, mostly remaining unseen until the program is actually launched revealing it to the user and making the code faulty and unable to be executed, making the run time error the most troublesome of the three errors.The logical error in Python is used similar to as the Syntax and the run time errors, it is the easiest of the three because it detects the errors during the translation phase in which that means that the interpreter reads the Python source code and translates it into executable machine code however, if a mistake is located during the source code, it will show the user the exact spot on where the error was located, making the logical error the easiest to repair out of all of the other
Mistakes are made by everyone whether it be because of confusion, lack of correct information, or just an accident. Mistakes are what make us human because we can't be perfect
The program will monitor the user input and will notify immediately of a wrong action (like a key stroke the is not valid for the particular input), will create an error file that contains the data set that contains the error to be analyzed and investigated, or the entire batch of data will be rejected, if the errors cannot be attributed to an specific record, for the user to locate issues and resubmit a corrected set.
As I opened the front door of the IBM Building, my next chapter in life began. My eyes widen as I observed my teacher writing code on the smartboard. Uneasiness and fear rushed down my spine. I was the only person among fourteen girls without prior knowledge of coding. I spent eight hours in a confined room learning how to code. My computer science teacher appointed assignments in HTML and Python.

It all began in 1991, during the time of monumental computing development. DOS had been bought from a Seattle hacker by Bill Gates, for a sum of $50,000 – a small price for an operating system that had managed sneak its way across the globe due to a clever marketing strategy. Apple’s OS and UNIX were both available, though the cost of running either was far greater than that of running DOS. Enter MINIX, an operating system developed from the ground up by Andrew S. Tanenbaum, a college professor. MINIX was part of a lesson plan used to teach students the inner-workings of an operating system. Tanenbaum had written a book on MINIX called “Operating System” and anyone who had picked up a copy would find the 12,000 lines of code that comprised MINIX itself. This was a big issue; due to the fact that all know (well published) operating systems to that point had been well guarded by software developers, thus making it difficult for people to truly expand on operating system mechanics.
Microsoft was founded by Bill Gates and Paul Allen on April 4, 1975 to develop and sell BASIC interpreters for Altair 8800. It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by the Microsoft Windows. The company's 1986 initial public offering, and subsequent rise in its share price, created an estimated three billionaires and 12,000 millionaires from Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market and has made a number of corporate acquisitions. In May 2011, Microsoft acquired Skype Technologies for $8.5 billion in its largest acquisition to date.
When executing (running), the compiler first parses (or analyzes) all of the language statements syntactically one after the other and then, in one or more successive stages or "passes", builds the output code, making sure that statements that refer to other statements are referred ...
Python is a programming language made easy to code and read. Python is what is called an interpreted language, which the computer runs right away. This allows the programmer to make changes in the code quickly and efficiently with as few lines of code as possible. It is derived from C, but is an easier to read. It uses whitespace to delimit code, such as spaces or tabs to organize data. At the end of the lines, neither semicolons nor curly braces are necessary, making it an easy language to read. Fullscreen games can be made with Python, if one manages to access the correct libraries.
The field of Computer Science is based primarily on computer programing. Programming is the writing of computer programs using letters and numbers to make "code". The average computer programer will write at least a million lines of code in his or her lifetime. But even more important than writting code, a good programer must be able to solve problems and think logicaly.
Pascal programming language was designed in 1968, and published in 1970. It is a small and efficient language intended to encourage good programming practices using structured programming and data structuring. Pascal was developed by Niklaus Wirth. The language was named in honor of the French mathematician and philosopher Blaise Pascal. In 1641, Pascal created the first arithmetical machine. Some say it was the first computer. Wirth improved the instrument eight years later. In 1650, Pascal left geometry and physics, and started his focus towards religious studies. A generation of students used Pascal as an introduction language in undergraduate courses. Types of Pascal have also frequently been used for everything from research projects to PC games. Niklaus Wirth reports that a first attempt to merge it in Fortran in 1969 was unsuccessful because of Fortran's lack of complex data structures. The second attempt was developed in the Pascal language itself and was operational by mid-1970. A generation of students used Pascal as an introductory language in undergraduate courses. Pascal, in its original form, is a Procedural language and includes the traditional like control structures with reserved words such as IF, THEN, ELSE, WHILE, FOR, and so on. However, Pascal has many data structuring and other ideas which were not included in the original, like type definitions, records, pointers, enumerations, and sets. The earliest computers were programmed in machine code. This type of programming is time consuming and error prone, as well as very difficult to change and understand. Programming is a time-consuming a process. More advanced languages were developed to resolve this problem. High level languages include a set of instruction...
In 500 B.C. the abacus was first used by the Babylonians as an aid to simple arithmetic. In 1623 Wihelm Schickard (1592 - 1635) invented a "Calculating Clock". This mechanical machine could add and subtract up to 6 digit numbers, and warned of an overflow by ringing a bell. J. H. Mueller comes up with the idea of the "difference engine", in 1786. This calculator could tabulate values of a polynomial. Muellers attempt to raise funds fails and the project was forgotten. Scheutz and his son Edward produced a 3rd order difference engine with a printer in 1843 and their government agreed to fund their next project.
Computer programming can as well be defined as a process that leads from an original formulation of a computer problem to execute problems. Computer programming is also referred to as programming. It encompasses other activities such as understanding, analysis and generally solving problems that result in algorithm, verifying the algorithm requirements and coding algorithm in a target program language. The program also involves the implementation of the build system and managing derived artifacts like computer programs machine codes. Most often, the algorithm is represented in human-parseable languages such as Java, Python, Smalltalk among others.
Syntax is the study of how words are combined to create phrases and causes in the sentences of a specific language (Freeman and Freeman, 2014). Syntax helps us to make clear sentences that “sound right,” where words, phrases, and clauses each serve their function and are correctly ordered to form and communicate a complete sentence with meaning. The rules of syntax combine words into phrases and phrases into sentences. Not only does it focus on the correct word order for a language, but it also helps show the relationship between the meaning of a group of words. Without proper syntax, a sentence can be meaningless. It is key to understand that while every language does have certain syntax, the syntax does vary from language to language. It
Thousands of years ago calculations were done using people’s fingers and pebbles that were found just lying around. Technology has transformed so much that today the most complicated computations are done within seconds. Human dependency on computers is increasing everyday. Just think how hard it would be to live a week without a computer. We owe the advancements of computers and other such electronic devices to the intelligence of men of the past.
The computer evolution has been an amazing one. There have been astonishing achievements in the computer industry, which dates back almost 2000 years. The earliest existence of the computer dates back to the first century, but the electronic computer has only been around for over a half-century. Throughout the last 40 years computers have changed drastically. They have greatly impacted the American lifestyle. A computer can be found in nearly every business and one out of every two households (Hall, 156). Our Society relies critically on computers for almost all of their daily operations and processes. Only once in a lifetime will a new invention like the computer come about.
