Strings and numbers being different data types have to be solved in different ways. Let’s discuss certain ways in which this problem can be solved. Method #1 : Using Type conversion The simplest way in which this task can be performed is by converting the integer explicitly into string datatype using the basic type conversion and adding it to appropriate position. Python3
Output : The original string is : Geeks The original number : 4 The string after adding number is : Geeks4Geeks Method #2: Using %d operator This operator can be used to format the string to add the integer. The “d” represents that the datatype to be inserted to string is an integer. This can be changed according to the requirements. Python3
Output : The original string is : Geeks The original number : 4 The string after adding number is : Geeks4Geeks Method #3: Using join() method Python3
Output The original string is : Geeks The original number : 4 The string after adding number is : Geeks4Geeks How do you insert a number in Python?How to Add Two Numbers in Python. ❮ Previous Next ❯.
