Convert Integer To String In Python

Python is a high-level programming language mainly used in developments, backend developments with Django framework, data science, data management and visualization, and machine learning. This is an easy-to-learn language and very popular. With its readable syntax, it is considered to be one of the easiest programming languages and many developers start their programming journey with python. Released on 20 Feb 1991, it has evolved exponentially. Today there are 2 versions of python available 2.x and 3.x, With stubble differences in their syntax. Python 2.x is considered to be more established as it has been around for a long time and it has a huge number of helpful frameworks as well as an enormous community to help you. While 3.x is dynamic many programmers prefer 3.x over python 2.x. Let us see about How to Convert Integer To String In Python

What are Integer and String:

Integer and String are data types in programming languages. Mathematically Integers are whole numbers ranging from minus infinity to plus infinity including zero, Which means every fraction is excluded from the set. -2 is an Integer but .5 is not. We can perform a variety of operations with integers. In the computer world, minus infinity is not a number that computers can simulate and that is why – 2147483647 in the 32-bit machine, which uses 31 bits to store the value and 1 bit to store the sign of the integer. While for 62-bit machines the least integer possible is -9223372036854775807, which similarly uses 61 bits to store the magnitude of the integer and one bit to store the sign. The greatest integer for the 64-bit machine is 9223372036854775807 

And for a 32-bit machine, it is 2147483647.

Strings are a set of characters which is interpreted literally by the script. Strings can be mutable, or non-mutable. And we perform a bunch of operations with strings. In python String data type is immutable. If you try to say slice string in python or try to concatenate 2 strings you get an entirely new object.

In python, every data type is an object.

Convert Integer to String in Python:

There are many ways to convert Integer to String in Python. Let’s discuss some of them.

  • There is a built-in function in Python “str(Integer_val)”. You need to pass the integer value in the argument of the function. Such as: “str(45)”. It will convert the Integer value of 45 into a string and then you can proceed with your next action with the string. 
  • The second method is formatting. You need to pass the integer value in “ “{}”.format(num) “. Such as “{}”.format(45) which will be a string of value “45” and then you can store this value in another variable.
  • The tried method is the “%s” keyword. What you need to do is type 

“% s” % num 

Example: “% s” % 45

This will again return a String value of the integer 45.

  • The fourth method is to use the f string. How does that work? The syntax is f’{num}’
Example: f`{45}`

This also converts your integer value into a string.

Check if it is an Integer or String:

In python, there is a very basic built-in function to check the type of given data. The syntax is type(input). This function can take a variety of data type as input like string, Integer, dictionary, float, tuple, list, etc. To print the data in your device or your console you need the code

print(type(input))   in python 3.x

print type(input) in python 2.x

How to convert String to Integer:

Like the str() function, there is a built-in int() function in python to convert the string data type into an integer data type. The syntax is int(); This takes compatible data of string and then performs the conversion. As an example, we can say “flower” can not be converted to a number but “45” can be converted. This is an example of being compatible with the data type. You can again check if your output is a string or integer using the type() function.

Syntax:    int(input);

Conclusion:

With this, we come to the conclusion that Python is very versatile and currently the most in-demand language in the world. With the enormous amount of data we are producing every day and the advent of artificial intelligence we can safely say the skill of programming and managing data is very crucial in the future. Many big companies like Tesla, Google, Facebook, Microsoft, Uber, and Zomato use data and enhanced algorithms every day to predict the users’ general aggregated behaviors to promote their business. And programming languages, especially python, is an integral part of the entire process.

Frequently asked questions:

Can you convert an integer to a string?

In almost every programming language integer data type can be converted into a string data type/

What is %s and %D in Python?

%s can be used as the placeholder for string values that you want to inject into the formatted string. Whereas, %d can be used as a placeholder for float or integer values.

How do you convert a list to a string in Python?

In python to convert a list to a string use the python list compressio=ng method. Simply use .join() method. This takes elements in the list one by one and joins them.

How do you convert a string into a list of characters in python?

The easiest way to do this is to use the split function. The syntax is str.split();

If your input is              “Word”;

The syntax will be       l =Word.split();

Where l is a list            [‘W’, ‘o’. ‘R’, ‘d’]

How do you declare a string?

In python string can be declared as 

Variable_name = string;

Example:  str = “Hello World”;

Print it using the print function:     print(str);

How do you declare an integer?

In python string can be declared as 

Variable_name =num;

Example:  num= -27

Print it using the print function:     print(num);

You can reassign it    num = 45

Now if you print it using  print(num)

You will get a value of 45.

What are the different data types in python?

The different data types in python are Strings, Integers, Float, Dictionary, Tuple, List, Complex, Set, etc.
