Conditionals
if, elif, and else Statements
Python provides if, elif and else statements to evaluate conditions.
if n1 > n2:
print('n1 is higher than n2')
elif n1 < n2:
print('n1 is lesser than n2')
else:
print('n1 is equals to n2')
Several conditions can be used in the same if statement by using and and or operators.
if (n1 > 5 and n2 > 6) or n1 < 1:
print('n1 is higher than 5 and n2 is higher than 6')
print('or n1 is lesser than 1')
Others operators can be used in the conditions.
if n1 in [1, 2, 3, 4]:
print('n1 is contained in the list')
elif n1 is False:
print('n1 is False')
elif type(n1) is int:
print('the type of n1 is int')
Some conditions can be combined.
if n1 > n2 < n3:
print('n1 is higher than n2 and n2 is lesser than n3)
elif n1 > n2 and n2 < n3:
print('the same as before')
Ternary Operator
The ternary operator allows you to write simple if-else conditions in a single line.
Syntax:
result = value_if_true if condition else value_if_false
Example:
age = 16
message = 'You can drink.' if age >= 18 else 'You can't drink.'
print(message)
Output:
You can't drink.
