User Input in Python

- User Input Function
- Basic Example
In this article, we will try to learn about the input function. Many times while working on a project you need to take an input from the user during runtime of applications. It's a very important function and used in almost all types of applications or programs.
So, let's try to see how we can use the input function.
Python provides us input() function which accepts
user input. You can then use this input within your program.
Python allows for user input, that means we are able to ask the user for an input.
Basic Example
Example
Use the prompt parameter to write a message before the
input:
x = input('Enter your name:')
print('Hello, ' + x)Output:
Input() function takes the name which we give as an input("x")
Up until now, our programs
were static. The value of variables was defined or hardcoded into the source
code.
To allow flexibility, we
might want to take the input from the user. In Python, we have the input() function
to allow this.
Let's understand more the additional function about input function…..
The syntax
for input() is:
input([prompt])
Parameter Description
prompt A String,
representing a default message before the input.
where prompt is the
string we wish to display on the screen. It is optional.
>>> num
= input('Enter a number: ')
Enter a number:
10
>>> num
'10'Here, we can see that the
entered value 10 is a string, not a number. To convert this into a
number we can use int() or float() functions.
>>> int('10')
10
>>> float('10')
10.0
This same operation can be
performed using the eval() function. But eval takes it
further. It can evaluate even expressions, provided the input is a string.
Note:- The input the function works with strings but with the help of additional functions this can
convert the data type into the type conversion we command to the python coding.
I hope you enjoyed reading this article and finally, you came
to know about User input in python.
