Introduction
Programmers often want to create programs where users can enter multiple inputs in Python. They then perform several operations on the input provided by the user. Some inbuilt functions can be used multiple times to take input directly from the user such as raw_input () and input () in data science. Writing the same functions multiple times in a code makes the file heavy and increases code complexity. In this blog, we are going to discuss several methods that collect multiple inputs from the user in one line and reduce code length.
- Split () function
- Map () function
- List comprehension
Collection Multiple Inputs in Python From User
Using Split () Function
With the help of the split () function, developers can easily collect multiple inputs in Python from the user and assign all the inputs to the respective variables. Developers can specify a character that will be used as a separator to break the input provided by the user. If the developer is not providing any separator, then the user input is broken by white space. Usually, this method is used to break a python string into multiple substrings, but it can also be used to collect multiple inputs from the user.
The syntax that is used for the split () method is as follows:
var1, var2 = input (“Type what type of input you want to collect from the user”). split (“/”) for / separated input
var1, var2 = input (“Type what type of input you want to collect from the user”). split () for white space separated input
Example of Split () Function
| # Python program for breaking Python string into substring
# taking multiple inputs from the user using the split () function # collecting three inputs at a time a, ,b, c = input (“Enter your child age: “).split () print(“Enter your elder son’s age: “, a) print(“Enter your daughter’s age: “, b) print(“Enter your younger son’s age: “, c) print() # collecting four inputs at a time a, b, c, d = input(“Enter the count of fruits: “).split() print(“Enter the number of apples you have: “, a) print(“Enter the number of oranges you have: “, b) print(“Enter the number of mangoes you have: “, c) print(“Enter the number of bananas you have: “, d) print() # taking two inputs at a time x, y = input(“Enter your marks: “).split() print(“Marks obtained in physics is {} and the mark obtained in chemistry is {}”.format(x, y)) print() |

The Output for the Above Program is as Follows
| Enter your child age: 25 20 14
Enter your elder son’s age: 25 Enter your daughter’s age: 20 Enter your younger son’s age: 14 Enter the count of fruits: 5 15 13 23 Enter the number of apples you have: 5 Enter the number of oranges you have: 15 Enter the number of mangoes you have: 13 Enter the number of bananas you have: 23 Enter your marks: 96 84 Marks obtained in physics is 96 and the mark obtained in chemistry is 84 |
Using Map () Function
map () is the other function used by the developers to take multiple inputs from the user. The syntax for map () function is as follows:
var1, var, var = map(int,input().split())
Example of Map () Function
| #collecting multiple inputs in Python using map () function
a, b = map (int, input(“Enter the count of fruits you have: “).split()) print(“Enter the count of apples you have: “, a) print(“Enter the count of oranges you have: “, b) |
The Output for the Above Program is as Follows
| Enter the count of fruits you have: 30 50
Enter the count of apples you have: 30 Enter the count of oranges you have: 50 |

Using List () Function
List () is one of the functions used in Python language to define and create a list. List function works similarly as a mathematical statement in one line. It is also used by developers to collect multiple inputs in Python from the user. List () function collects multiple inputs of different data at the same time.
The syntax for creating a list is as follows:
a, b = [afora input(“Type what type of input you want to collect from the user “).split()]

Example for List () Function
| # Python program for breaking Python string into substring
# taking multiple inputs from the user using list comprehension # taking three input at a time a, b, c = [int(a) for a in input(“Enter the marks obtained: “).split()] print(“Enter the marks obtained in physics: “, a) print(“Enter the marks obtained in chemistry: “, b) print(“Enter the marks obtained in English: “, c) print() # taking two input at a time a, b = [int(a) for a in input(“Enter your child’s age: “).split()] print(“Enter the age of elder son: “, a) print(“Enter the age of younger son: “, b) print() # taking three inputs at a time A, b, c = [int(a) for a in input(“Enter the count of fruits: “).split()] print(“The total number of apples are {} and oranges are {}”.format(a, b)) print() # taking multiple inputs at a time a = [int(a) for a in input(“Enter multiple value: “).split()] print(“The value entered by you are: “, a) |
The Output of the Above Program is as Follows
| Enter the marks obtained: 94 90 96
Enter the marks obtained in physics: 94 Enter the marks obtained in chemistry: 90 Enter the marks obtained in English: 96 Enter your child’s age: 34 23 Enter the age of elder son: 34 Enter the age of younger son: 23 Enter the count of fruits: 76 23 The total number of apples are 76 and oranges are 23 Enter multiple value: 23 45 76 48 90 76 The value entered by you are: [23, 45, 76, 48, 90, 76] |
