Control Statements There are many instances when it is required to take decision. If statement is a decision making statement. If statement in Python is used to test a condition and transfer the control of program to usual sequential next line of code or skips certain lines and jump to another point. It should be clearly noted that Python make use of indentation almost every where especially while writing if statement. If indentation is not used in a statement that particular line of code will be treated as not part of if statement or loop statements and is thus treated as statement outside the control and loop. example: >>> x=10 >>> if x>0: . . .      print(x," is +ve Number")    #indented line thus executed
