If else statements in python allow us to perform different task depending on certain condition.
Verbally:
“Hey, if this happens then perform this action.”
Some characteristics of if else in python:
- if statement allows the computer to perform some action.
- elif statement is executed if above statements is false.
- else statement is executed only when all the conditions are false.
Syntax:
1 2 3 4 5 6 | if case1: perform this statement1 elif case2: perform this statement2 else: perform this statement3 |
Examples:
1 2 3 | if case1: if True: print("This is Inside of IF") |
Output
1 | This is Inside of IF |
1 2 3 4 5 6 7 8 | if case1: x=3 if x==2: print("value of x is 2") elif x==3: print("value of x is 3") else: print("value of x is not matching") |
Output
1 | of x is 3 |
1 2 3 4 5 6 7 | if case1: role = "programmer" if role == "programmer": print("Helo! Programmer.") else: print("What do you do?") |
Output
1 | Helo! Programmer. |
Use if-elif-else in that situation when only one of the given tasks/statements can be executed depending on some condition.
