The developer often wants a user to enter multiple values or inputs in one line. In C++/C user can take multiple inputs in one line using scanf but in Python user can take multiple values or inputs in one line by two methods.
- Using split() method
- Using List comprehension
Using split() method :
This function helps in getting multiple inputs from users. It breaks the given input by the specified separator. If a separator is not provided then any white space is a separator. Generally, users use a split() method to split a Python string but one can use it in taking multiple inputs.
Syntax :
input().split(separator, maxsplit)
Example :
Python3
# Python program showing how to# multiple input using split# taking two inputs at a timex, y = input("Enter two values: ").split()print("Number of boys: ", x)print("Number of girls: ", y)# taking three inputs at a timex, y, z = input("Enter three values: ").split()print("Total number of students: ", x)print("Number of boys is : ", y)print("Number of girls is : ", z)# taking two inputs at a timea, b = input("Enter two values: ").split()print("First number is {} and second number is {}".format(a, b))# taking multiple inputs at a time# and type casting using list() functionx = list(map(int, input("Enter multiple values: ").split()))print("List of students: ", x) |
Output:
Enter two values: 5 10 Number of boys: 5 Number of girls: 10 Enter three values: 5 10 15 Total number of students: 5 Number of boys is : 10 Number of girls is : 15 Enter two values: 5 10 First number is 5 and second number is 10 Enter multiple values: 5 10 15 20 25 List of students: [5, 10, 15, 20, 25]
Using List comprehension :
List comprehension is an elegant way to define and create a list in Python. We can create lists just like mathematical statements in one line only. It is also used in getting multiple inputs from a user.
Example:
Python3
# Python program showing# how to take multiple input# using List comprehension# taking two input at a timex, y = [int(x) for x in input("Enter two values: ").split()]print("First Number is: ", x)print("Second Number is: ", y)# taking three input at a timex, y, z = [int(x) for x in input("Enter three values: ").split()]print("First Number is: ", x)print("Second Number is: ", y)print("Third Number is: ", z)# taking two inputs at a timex, y = [int(x) for x in input("Enter two values: ").split()]print("First number is {} and second number is {}".format(x, y))# taking multiple inputs at a timex = [int(x) for x in input("Enter multiple values: ").split()]print("Number of list is: ", x) |
Output :
Enter two values: 5 10 First Number is: 5 Second Number is: 10 Enter three values: 5 10 15 First Number is: 5 Second Number is: 10 Third Number is: 15 Enter two values: 5 10 First number is 5 and second number is 10 Enter multiple values: 5 10 15 20 25 Number of list is: [5, 10, 15, 20, 25]
Note: The above examples take input separated by spaces. In case we wish to take input separated by comma (, ), we can use the following:
Python3
# taking multiple inputs at a time separated by commax = [int(x) for x in input("Enter multiple value: ").split(",")]print("Number of list is: ", x) |
