Week 1/ Unit 1: Introduction and Fundamental Concepts
Week 1 / Unit 1 is about getting to know the programming language Python and how it works. There is many new terms you should know when you take the test, and there is a list of the ones you should write down in your notes.
If you are new to Python you should use PyCharms for this, it is a great tool for programming and also one you might use when working with programming in the Future. This is a free version and also it is free for students.
Glossary and Terms:
The Process of finding a solution and expressing it.
- Low-level language
Code close to the processor (example assembly programming language)
- High-level language
Python, PHP, Java, and many others is high level language, they are easy for people to understand and learn.
A program that can run on many different operating systems ( ex. many java application can do this)
A program that needs another program for running
When the program is ready for the users input, normally in console applications.
A set of instructions that specifies a computation
- Print statement
In Python it prints the value on the screen for the user to see. So it causes the Python code to output the explicit value.
+ – / * special symbols for simple computations like adding, subtracting, multiply, divide, concatenate strings and so on.
Basic unit of data, it an be like a number or string
The category of the value, like if the value is a string, integer, float, object, etc. (In Python use type(’12’) = <class ‘str’> and type(12) = <class ‘int’>)
In it the definition on a whole number, the number 100.00 is a floating-point number because you use a decimal pointer
125.50 is a floating-point number also called float, is you only use 125 the you have a integer (a whole number without decimals)
It is a sequence is characters
- Natural language
Any one of the languages humans speaks in the world ( mostly all programming and scripting languages use English when build )
- Formal language
This is a language that is designed for a specific purpose, like a programming language.
