# Python | Insert a number in string

Sometimes, while dealing with strings, we may encounter a problem in which we might have a numeric variable whose value keeps changing and we need to print the string including that number. 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 code to demonstrate working of ` `# Inserting a number in string  ` `# Using type conversion ` ` `  `# initializing string  ` `test_str ``=` `"Geeks"` ` `  `# initializing number ` `test_int ``=` `4`  ` `  `# printing original string  ` `print``(``"The original string is : "` `+` `test_str) ` ` `  `# printing number ` `print``(``"The original number : "` `+` `str``(test_int)) ` ` `  `# using type conversion ` `# Inserting number in string  ` `res ``=` `test_str ``+` `str``(test_int) ``+` `test_str ` ` `  `# printing result  ` `print``(``"The string after adding number is  : "` `+` `str``(res)) `

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 code to demonstrate working of ` `# Inserting a number in string  ` `# Using % d operator ` ` `  `# initializing string  ` `test_str ``=` `"Geeks"` ` `  `# initializing number ` `test_int ``=` `4`  ` `  `# printing original string  ` `print``(``"The original string is : "` `+` `test_str) ` ` `  `# printing number ` `print``(``"The original number : "` `+` `str``(test_int)) ` ` `  `# using % d operator ` `# Inserting number in string  ` `res ``=` `(test_str ``+` `"% d"` `+` `test_str) ``%` `test_int ` ` `  `# printing result  ` `print``(``"The string after adding number is  : "` `+` `str``(res)) `

Output :

```The original string is : Geeks
The original number : 4
The string after adding number is  : Geeks4Geeks
```
