Python Logic and loop mode

1. Grammar

If Condition:

Code 1

Code 2

Code 3

(The same distance code as the indentation is the same code block, the code runs from top to bottom, and when a condition is not true, the next condition is run)

Syntax format:

If:

Code 1

Elif:

Code 1

else:

Code 1

If nesting (when an if condition is established, enter the next logical judgment in this condition)

While loop syntax, While loop is also called a conditional loop.

While condition:

Code1

While + broken : break means to terminate the loop of the current layer and execute other code

While True:

Print1

Print2

Break

While + continue: continue means to terminate the cycle and go directly to the next loop

Coutinue do not add the code that executes in the last step of the loop body, meaningless.

While+tag: When tag=false all exits

While+else: The terminal will not display until after the program has finished executing.

the Process Control For loop: Remove multiple values from a type

Default count mode

Step Size The default is 1, set to 2 when 1,3
