In this article, we will see how Python takes input from the user and How it displays the output to the user. First, we cover input than output. 




Input in Python

No matter what we provide but Python always takes input as String. So we have to convert the input into our desired datatype. 

Syntax :
$ input(“Message to the user”)

Example:

As you can see when the user enters the numbers python stored it has a string. You will see more examples.




How to take input from users in Python?

To take input from the user, Python provides an inbuilt function input(). We can also pass the message to the user about what we are expecting him to enter.
Example:




1. We can store the value in variables using the input function.

2. If we check the datatype of the “Name” variable it is a string.




3. Even when the user enters a number then also Python take it as a String.

Let's convert digits into Integer from String.

It's all about the input in Python.




Output in Python

Python has a built-in function print to display output to the user. 

Syntax:

code1

$ print(“Output String”, sep=’ ’, end = ‘/n’, file = file, flush = flush )

code2

Example:

Note: Even if we provide numbers in print() internally python converts it into a string and then displays it to the user. 




1. Let's see how we can use a separator in print i.e “sep”.

So, whatever we provide in sep it will insert in between the values as shown above.


2. By default end is “\n” in print, If we want to change then we can change it using “end”.




3. When placeholders { } are empty, Python will replace the values passed through st r.format() in order.

Syntax:

print(“{ }, is the founder of Neptuneworld. ”.format(“Value to replace”))




4. How to format or truncate float values ta desired decimal places.

Example 1:

num=665.6754567, truncate to 2 decimal places.

 

Example 2:

num= 5546.456543, truncate to 3 decimal places.

Conclusion

Now that you know all this, You are comfortable with Python Input and Output.
