In this tutorial, we will learn If else statement in Python.
The if-else statement in Python is used to run various blocks of code depending on a specific condition. The if-else statement’s general syntax is as follows:
if condition:
# code to be executed if the condition is True
else:
# code to be executed if the condition is False
Here is an illustration of how to use Python’s if-else statement:
x = 10
if x > 0:
print("x is positive")
else:
print("x is zero or negative")
In this example, if the value of x
is greater than 0, the statement x is positive
will be printed. Otherwise, the statement x is zero or negative
will be printed.
You can also use multiple elif
(short for “else if”) statements to check for additional conditions. Here’s an example:
x = 10
if x > 0:
print("x is positive")
elif x == 0:
print("x is zero")
else:
print("x is negative")
In this case, if x
is greater than 0, the statement x is positive
will be printed. If x
is equal to 0, the statement x is zero
will be printed. Otherwise, the statement x is negative
will be printed.
Remember to indent the code blocks correctly to define the scope of each condition. Python uses indentation (typically four spaces) to group statements together.
