Python Conditions and If statements

Python supports the usual logical conditions from mathematics:

Equals: a == b

Not Equals: a != b

Less than: a < b

Less than or equal to: a <= b

Greater than: a > b

Greater than or equal to: a >= b

These conditions can be used in several ways, most commonly in "if statements" and loops.

An "if statement" is written by using the if keyword.

Example

If statement:

a = 33

b = 200

if b > a:

  print("b is greater than a")

b = 200

if b > a:

  print("b is greater than a")

Elif

The elif keyword is pythons way of saying "if the previous conditions were not true, then try this condition".

Example

a = 33

b = 33

if b > a:

  print("b is greater than a")

elif a == b:

  print("a and b are equal")

Else

The else keyword catches anything which isn't caught by the preceding conditions.

Example

a = 200

b = 33

if b > a:

  print("b is greater than a")

elif a == b:

  print("a and b are equal")

else:

  print("a is greater than b")
