How to convert a Python string to Int:
To convert a string to an integer in Python, use the int () function. This function accepts two parameters: the initial string and the optional base to represent the data. Use the syntax print (int ("STR")) to return str as int or integer.

How to convert a Python integer to a string:
To convert an integer to a string in Python, use the str () function. This function accepts any type of data and converts it to a string, including integers. Use the print (str (INT)) syntax to return int as a str or as a string.

Python includes a number of data types that are used to distinguish a particular data type. For example, Python strings are used to represent text data, and integers can represent integers. When programming, you might want to convert values ‚Äã‚Äãbetween different data types so that you can use them in different ways.

A common operation is to convert a Python string to an integer or an integer to a string. Python includes built-in methods that can be used to perform these conversions: int () and str ().

In this tutorial, " We will explore how the int () method can be used to convert a string to an integer in Python. We will also see how to use str () to convert an integer to a string.

Python data types

When you are data types in Python used to store data, including numbers, booleans, and lists.

In this article we will focus on two of these data types: strings and numbers.

In Python , strings are surrounded by quotes single or double and are used to represent text information. Here is an example string:

The number data type is used to store both decimal and integer numbers. Decimal numbers will be automatically converted to floating point numbers and integers will be considered as integers. Here is an example of integer and floating point number in Python :

Converting from one data type to another data form is called type conversion . If you want to convert a string to an integer or an integer to a string, you will perform a type conversion operation

Python String to Int

The int () can be used to convert a string to an integer value in Python.

int () accepts two parameters: the string to convert to integer and the base to which you want your data to be represented. The second parameter is optional.

The method returns the value you passed via int (), represented as an integer. Here is the syntax of the Python int () method:

Here is an example of the int () method used to convert a string to an integer:

Our code returns:

An example of an Int in action string

Let’s use a more detailed example to show how the int () method can be used. Suppose we create a registration form for a children’s game that asks for the user’s age. We need this value stored as an integer in our database. But when a user enters the value into our program, their age becomes a string.

Let’s create a program that does this. We’ll start by using the input () method to get a user’s age:

When our user enters a number, it will be printed to the console. Here is what happens when we run our program:

The value entered by the user is 12. It may appear to be a number. However, when we use the type () method to check the data type for our user’s age, we see that it is a number. We can use the following code to check the data type of our user’s age:

Our code returns:

As you can see, our data is stored as str or as a string. Therefore, it is clear that we need to convert our data to an integer. We can do this using the following code:

Here is what happens when we run our code and insert the value 12:

Our code returns the same output as above, but 12 is now stored as an integer. We can use the type () method to check:

Our code returns:

Now our value is stored as an integer as we originally intended.

Python Int to String

The str () method allows you to convert an integer to a string in Python. this method is:

Let’s see an example to show how this method works.In our previous example, we converted the user’s age to an integer using this code:

Let’s say we want to print a message with the age of our user on the console. We could do this using the following code:

< p> Our code returns an error:

This because you cannot concatenate a string into an integer like we tried to do above. In order for our code to work, we’ll need to convert our user’s age to a string. We can do this using the str () method:

Our code returns:

How old are you?

12

Your age is: 12

We have successfully converted our integer to a string using str (). Both values ‚Äã‚Äãare now strings, which means we can now concatenate the Your age is: message with the user’s age.

Python Convert a list of strings to a list of integers

Suppose you have a list of strings containing the grades students obtained in a computer science class. We want to convert each vote on our list to an integer. To do this, we can use a Python list understanding .

A list comprehension makes it easy to create a new list from the contents of an existing list. In this case, we’ll use a list comprehension to transform a list of strings into a new list of integers.

Consider this code:

We first define a list called "grades". This list contains strings. Next, we write a list comprehension that converts each value in our list of "votes" to an integer. Our list comprehension does this by iterating over each value in "votes" and changing their data type to using the int () function.

At the end of our p rogramme, we print our new list of integers:

Our code successfully converted our list of strings to a list of integers.
