f-strings in Python example

#JavaInspires

 

The f is for format, because Python formats the string by replacing the name of any variable in braces with its value.

F-strings were first introduced in Python 3.6. If you’re using Python 3.5 or earlier, you’ll need to use the format() method rather than this f syntax. To use format(), list the variables you want to use in the string inside the parentheses following format. Each variable is referred to by a set of braces; the braces will be filled by the values listed in parentheses in the order provided:

full_name = "{} {}".format(first_name, last_name)

Example code

#f-strings in python

first_name = "Nikolas"
last_name = "Tesla"
#using format strings
full_name = f"{first_name} {last_name}"
#print full name
print(full_name)

Output

Nikolas Tesla
