Python - if statement

In this article, we would like to show you if statement example in Python.

Quick solution:

x = -1

if x > 0:
    print("x > 0")
elif x == 0:
    print("x = 0")
else:
    print("x < 0")

1. If

In this example, we create a simple if statement that checks if the number we specified is greater than 0.

x = 1

if x > 0:
    print("x > 0")

Output:

x > 0

2. Elif

In this example, we add elif keyword that checks the next condition if the previous conditions were not true.

x = 0

if x > 0:
    print("x > 0")
elif x <= 0:
    print("x <= 0")

Output:

x <= 0

3. Else

In this example, we add the else condition that catches anything which isn't caught by the previous conditions

x = -1

if x > 0:
    print("x > 0")
elif x == 0:
    print("x = 0")
else:
    print("x < 0")

Output:

x < 0

4. Operators

You can use operators such as and & or to combine conditions inside if statement.

and operator

x = 1
y = 2

if x > 0 and y > 0:
    print("Both x and y are positive numbers.")

Output:

Both x and y are positive numbers.

or operator

x = 1
y = -5

if x < 0 or y < 0:
    print("One of the numbers is negative.")

Output:

One of the numbers is negative.
