What’s an if elif statement:
Like the if else statement, and elif statements can be added to an if conditional statement in python to run multiple conditions in python
Example: When going to school you can check:
(Condition) if school bus is outside:
(Decision): Get in the bus
(Alternative) elif bus is close by (means if school bus is not around, check this condition if school bus is close by):
(Decision): Walk towards bus
(Alternative) elif bus is honking (means if school bus is not around and school bus is not close by, check this condition if you can hear school bus honking):
(Decision): Wait a bit
Else:
(Decision): Go back inside
So this means when you check and the school bus is outside then you should hop in but if you can’t find bus yet, but you can see it close by then you can walk towards it, but if you can’t see school bus but hear it’s honk, then wait for it. If all conditions are not true, then go back inside
Things to note:
1. Single equal sign = is used in python to assign a variable to it’s data value
english = 70
maths = 85
2. Double equal sign == is used in python to compare if two variables have the same data
if (maths == english)
3. The column : is used to start indentation after the if else conditional statement
if (nathan == 12):
4. Indentations are the spaces inside your conditions (if, else) to tell python the statements only runs if the condition is True
if (nathan == 12):
print”Nathan is ready for the python exam” (There is a space before the print, python knows it only runs if the condition is True)
