Python Development-Process Control

The Python process controls the IF branch statement for Loop statement while the Loop statement break and the Continue loop control the 1.if branch statement if single branch statement:

Format:

if conditional Expressions: Directives Else : Instruction

For example:

A = 1if a = = 1    :print("Yes")else  :     Print ("No")
------------The result of the output-----------
Yes

If multi-branch statement:

Format:

if conditional expression:    directive elif  conditional expression:     directive elif  conditional expression:    directive  else  :    directives

For example:

A = 1= 2if a! = 1    :print("A! = 1")elif b = = 2    :print("b = = 2")Else  :     Print ("No")
-----------The result of the output---------
b = = 2

If nested formula sentence:

Format:

if conditional expression:    directive if  condition expression:     directive else  :        directive Else  :    instruction

For example:

A = 1b= 2ifA = = 1 :    Print("a=1")    ifb! = 2 :        Print("b! = 2")    Else :        Print("b=2")Else :    Print("a!=1")
------------The result of the output-----------
A=1
b=2
