Answers Key:

Generic 3

5 x 3 = 15

pass statement is generally used as a placeholder. When we have a loop or function that is to be implemented in the future and not now, we cannot develop such functions or loops with empty body segment because the interpreter would raise an error. So, to avoid this we can use pass statement to construct a body that does nothing.

i= 10 # intializing part of the control variable
while (i<=15): # test condition
print (i, end='\t') # statements - block 1
i=i+1 # Updation of the control variable
else:
print ("\n Value of i when the loop exit",i)
Output:1
10 11 12 13 14 15
Value of i when the loop exit 16

Example: Program to illustrate the use of while loop - to print all numbers from 10 to 15
i=10 # intializing part of the control variable
while (i<=15): # test condition
print (i, end='\t') # statements - block 1
i=i+1 # Updation of the control variable
Output:
10 11 12 13 14 15

Python provides the following types of alternative or branching statements:
(i) Simple if statement
(ii) if..else statement
(iii) if..elif statement
