PYTHON Language Programming

PYTHON language programming is:
- flexible,
- portable,
- easy,
- free,
- accessible, 
- intuitive,
- versatile,
- universal, 
- convenient,
- ordinary, 
- common.
PYTHON programming language has taken over the best of all the programming languages before it. It is simple, efficient, dense and attractive.
The input() statement is used to enter the data. The print() instruction is used to present the results.
Variable names are constructed the same as all other programming languages:
- the first character is required a letter,
- the other characters are letters, numbers or underscores,
- uppercase letters differ from lowercase letters,
- any words other than the reserved words of the PYTHON language.
- the length of the name does not exceed 31 characters.
The string is preceded and followed by quotation marks.
The string is preceded and followed by an apostrophe.
Correct variable names:
a
i
j
temp
Triangle
surface_cercle 
volume_cube
Name_Person
Age_Student
Year2000
Wrong variable names:
7i
=i4
&cost
name$student
age*person-teacher
Variable names elev,  Elev,  ELEV,   ELev,  eleV,   EL_EV,   ELEV_        they are different.
PYTHON reserved keywords:
False, None, True, and, as, assert, async, await, break, class, continue, def, del, elif, else, except, finally, for, from, global, if, import, in, is, lambda, nonlocal, not, or, pass, raise, return, try, while, with, yield. Variable names: And
ReturN
WHile
YIEld
From

eXCept, are correct.

Pointers in PYTHON?

 Memory programming is used in programming. A memory area is defined by: - associated variable name, - length as number of bytes, - address of the first byte, - content as a string of bits with contextual interpretation. The contents of the pointer variable are the address of a memory area. A variable is referred to when its address is loaded into a pointer variable. A pointer variable is redirected using its contents to reach the contents of the variable whose address it contains. The reference operator initializes the pointer variable. The pointer referral operator provides the contents of the memory area whose address it contains. And the PYTHON language natural works with pointer variables. PYTHON works differently and spectacular with pointers. (March 31, 2022)
