In Python, the string is defined as any sequence containing the alphabet, numbers, characters, etc. The integer is defined as a whole number, either positive or negative. For all mathematical calculations, the integer and float values are used in Python, so to convert the numeric string into an integer, the inbuilt “**int()**” function is used in Python.

This write-up will enable you to convert strings into an int in Python. The following terms are discussed in depth with numerous examples:

All right, let’s get started!

**How to Convert String Into Integer in Python?**

In Python, the string is converted into an integer value using the built-in “**int()**” function. The “int()” function takes only numeric strings data type as an argument and returns an error if the non-string data type is passed.

**Example 1: Simple Conversion Using int() Function**

In the following example, the “**int()**” function is utilized to convert the string value into an integer value.

**Code:**

```
String_value = '90'
print('String Value: ', String_value)
print('\nData Type of String Value: ', type(String_value))
# using int() function
Integer_value = int(String_value)
print('\nInteger Value: ', Integer_value)
print('\nData Type of integer Value: ', type(Integer_value))
#adding integer value to another integer
print('\nAddition of integer value: ', Integer_value + 20)
```

In the above code:

- The string value containing number is initialized.
- The “
**int()**” function accepts the input string variable as an argument and retrieves the integer. - The “
**type()**” function is used before and after the conversion of the string to an integer to verify the data type. - A mathematical operation, “addition”, is performed on the converted value.

**Output:**

In the above output, the string value has been converted into an integer value.

**Example 2: Advanced Conversion Using int() Function**

In the example given below, the “**int()**” function is used to convert a string into an integer during the execution of the algebraic expression.

**Code:**

```
first_string = '14'
second_string = '10'
subtraction = int(first_string) - int(second_string)
print('Difference of Numbers: ', subtraction)
```

In the above code:

- Two string values containing numbers are initialized in the program.
- The “
**int()**” function is used along with the algebraic expression to convert the input string into an integer and perform calculations.

**Output:**

The string value has been converted into an integer value, and the respective mathematical operation has been performed on the converted values.

Here’s the end of this Python guide!

**Conclusion**

To convert the input string into an integer, the inbuilt “**int()**” function is utilized in Python script. The “**int()**” function returns “**TypeErrors**” while executing non-string or non-integer data types. This write-up presented all the necessary details related to the strings into integers conversion in Python.
