Python - if statement

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

Quick solution:

xxxxxxxxxx

x = -1

​

if x > 0:

    print("x > 0")

elif x == 0:

    print("x = 0")

else:

    print("x < 0")

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

xxxxxxxxxx

x = 1

​

if x > 0:

    print("x > 0")

Output:

xxxxxxxxxx

x > 0

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

xxxxxxxxxx

x = 0

​

if x > 0:

    print("x > 0")

elif x <= 0:

    print("x <= 0")

Output:

xxxxxxxxxx

x <= 0

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

xxxxxxxxxx

x = -1

​

if x > 0:

    print("x > 0")

elif x == 0:

    print("x = 0")

else:

    print("x < 0")

Output:

xxxxxxxxxx

x < 0

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

xxxxxxxxxx

x = 1

y = 2

​

if x > 0 and y > 0:

    print("Both x and y are positive numbers.")

Output:

xxxxxxxxxx

Both x and y are positive numbers.

xxxxxxxxxx

x = 1

y = -5

​

if x < 0 or y < 0:

    print("One of the numbers is negative.")

Output:

xxxxxxxxxx

One of the numbers is negative.
