Python format() Function – 10 Simple Examples


Python allows you to handle complex string formatting efficiently with the help of the format() function. You can put placeholders defined by a pair of curly braces in a string. Call the string.format() function and pass the value you want to put into the placeholders as parameters.

Given below are a few examples of string formatting in Python.

myString = 'Hello, good {}.'.format('morning')
print(myString)

We can use the placeholders multiple times in a string. Make sure you pass all the parameters in the format() function.

myString = 'The colors are {}, {}, and {}.'.format('Red','Blue','Green')
print(myString)

While using the format() function, we can insert values into the string by using index-based positions.

myString = 'John, {0}, {1}, and {2} are freinds.'.format('Maxx','Bob','Chris')
print(myString)
myString = 'John, {2}, {1}, and {0} are freinds.'.format('Maxx','Bob','Chris')
print(myString)

We can also reuse the parameters of the format() function inside the string.

myString = 'John, {0}, {1}, and {0} are freinds.'.format('Maxx','Bob')
print(myString)
myString = "{0}{1}{0}".format("abra","cad")
print(myString)

We can also insert values into the string by using assigned keywords for the parameters in the format() function.

myString = "The teams qualified for Champions League final are {finalist_1} and {finalist_2} ".format(finalist_1="Real Madrid",finalist_2="FC Barcelona")
print(myString)
fruits=['apple','orange','mango']

myString = "The fruits inside the bucket are {0}, {1} and {2}.".format(fruits[0],fruits[1],fruits[2])

print(myString)
myString = "{language} programming is fun.\n{language} is easy to learn.".format(language="Python")

print(myString)

By using string formatting, you can combine non-strings with strings.

myString = "The numbers are {}, {} and {}".format(10,25,35)
print(myString)
