However it is much cleaner to use the .format() method on strings instead: >>> print("{name} is {age} years old".format(name=name, age=age)) Bob is 33 years old It is even cleaner to use f-strings, a new feature in Python 3: >>> print(f"{name} is {age} years old") Bob is 33 years old Improve your Python … 1. Python is infinitely reflective. Python Programming Bootcamp: Go from zero to hero. Converting to a string; Converting to a number; Deleting Variables in Python ; Variable Names in Python.
