Conditional
1 p85 With conditional statement we can check condtions and change the behavior.
""" Conditional statement
"""
n = 20
if n % 10 == 0:
print("divisible by 10") # divisible by 10
elif n % 10 > 0:
print("not divisible by 10")
else:
print("else")

name = input('What is your name?\n')
# type: John
print(name)
# output: John

Check Fermat's last theorem.
""" Fermat's last theorem
For any number > 2, there are no positive integers
a, b, c, so that a**n + b**n = c**n
