How to use python IDLE?
This video explains the basic rules in using IDLE for Python development. The following list presents rules beginners need to remember while learning Python:
We do not forget to save any modification we perform on any file.
We type Python statements in the file carefully, if some rules are not followed the Python interpreter won’t understand us.
Vocabulary of a computer language is case sensitive. For examples, Python interpreter distinguishes between print(), Print(), prinT(), or PRINT(). If a word is not defined before trying to use it, Python will give an error.
Anything we open in a computer program we close it, e.g. we open a bracket we have to close it. The best practice is first close the bracket, then go back and type whatever we need inside the brackets.
We pay attention to tabs in Python, i.e. the number of characters that text advances to begin a line, usually 4 blank characters. Tabs in Python create blocks of code.
