if-elif-else statements branch determination (and additional continue BREAK) illustrates ---

A branch loop:　

INPUT = A ( " Please enter a five-digit number " )
 IF (len (A) =. 5! ):
     Print ( " digital input substandard " );
 elif (A [:: 0] == A [-1: : -1 ]):
      Print ( " {} is a palindrome " .format (the eval (A)))
 the else :
     Print ( " {} is not a palindrome " .format (the eval (A)))

　　This is typically used if-elif-else statement to determine the output of the branch, of course, can be nested if statements , Python is used to distinguish between a block of statements indented

　　So branch judgment statement indentation has strict requirements

Two, the Continue and break:

　　continue is out of this cycle, but the cycle is not interrupted; break is the direct end of the cycle, the following statement is not executed.

　　

INPUT = a_num ( " Please enter an integer: " ) 

 for a_num in Range (1,101 ):
      IF (a_num. 7% == 0):
         Continue 
     Print (a_num, End = "  " )
         

　　Here continue skip number is divisible by 7, the number of 0 to 100 other output, output only 7 will break over, will not go cycle.
