In Python, we use the input() function to take input from the user. Whatever you enter as input, the input function converts it into a string. If you enter an integer value still input() function converts it into a string.
Python input() Function Syntax

Parameter:
- Prompt: (optional) The string that is written to standard output(usually screen) without newline.
Return: String object

User Input in Python
In this example, we are taking input from the user and input user data as a string in Python with a prompt and printing it.
Python
name = input("Enter your name")
print("Hello", name)

Output
Enter your name:ankit rai
Hello ankit rai
Convert User Input to a Number
In this example, we are using the Python input() function which takes input from the user in string format converting it into an integer adding 1 to the integer, and printing it.
Python3
num = int(input("Enter a number:"))
add = num + 1
print(add)
|
Output
Enter a number:15
16
Take float input in Python
In this example, we are using the Python input() function which takes input from the user in string format converts it into float adds 1 to the float, and prints it.
Python3
num =float(input("Enter number "))
add = num + 1
print(add)
|

Enter number 5
6.0
Python Accept List as a input From User
In this example, we are taking input from the user in string format converting it into a list, and printing it.
Python3
li =list(input("Enter number "))
print(li)
|
Output
Enter number 12345
['1', '2', '3', '4', '5']
Take User Input for Tuples and Sets
In this example, we are taking input from the user in string format converting it into a tuple, and printing it.
Python3
num =tuple(input("Enter number "))
print(num)
|
Output
Enter number 123
('1', '2', '3')
Input with a dictionary comprehension
In this example, we are taking the words separated by space to input user data as a string in Python, and we make a dictionary of the word as the key with their length as the value.
Python3
words_str = input("Enter a list of words, separated by spaces: ")
words = {word: len(word) for word in words_str.split()}
print(words)
|
Output
Enter a list of words, separated by spaces: geeks for geeks
{'geeks': 5, 'for': 3}
