if statement executes a block of code if the condition is met, otherwise it ignores it. The syntax for an
if statement in Python is as follows:
if [condition is true]: do something
As a short and simple example, I have created a
.py file (the same file named
hello.py) in my
option_one = input('Type number 5 here: ') if option_one == 5: print('number 5 is your option')
Now, go to terminal, switch directory to
Documents and run the file.
The user is prompted to enter number 5. If the user enters number 5 then the message “ number 5 is your option” is printed on the screen. Number 5 is assigned as value of the
option_one variable. The
if statement checks if the value of the variable
option_one is 5 and if it is then it prints the message on the screen.
We didn’t add an else statement for the case when the user enters another number, not 5.
