It seems that I was self-taught 2 years ago, but I always have no decision ... It must be officially started today.

Don't say much nonsense, start:

S1:variables.

　　

1 variables: A variable is a word, only a single value

2 Exercise: Set a variable my_variable, set the value to 10

my_variable=10

3 data types are interage, floats, Boolean 3

4 Python is a case-sensitive language

5 Practice

1 set the variable My_int value to 7

2 Set the variable my_float value to 1.23

3 Set the variable My_bool value to True

My_int =7my_float=1.23my_bool=true

6 Pyhton's statement is similar to English

7 Python inside declares the use of spaces in separate

8 Python is an interpreted language that executes immediately after writing.

9 The sign of a single-line comment is: #
