Python List-generated

If you want to generate list[1,2,3,4,5,6,7,8,9], you can use range (1,10):

If you want to build [1*1,2*2,3*3,4*4,5*5,......, 9*9] Like this, you can use loops:

Using a list-generated formula, you can replace the above loop with a sentence:

The basic format is: [Statement for Var in ...]

First: Use [] to enclose the

Second: Write the expression on the front, if x*x

Third: Follow the For loop

IV: The For loop can also be followed by the if condition, such as:
