Taking multiple inputs from user in Python

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 time
x, y = input("Enter two values: ").split()
print("Number of boys: ", x)
print("Number of girls: ", y)

# taking three inputs at a time
x, 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 time
a, 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() function
x = 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 time
x, 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 time
x, 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 time
x, 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 time
x = [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 comma
x = [int(x) for x in input("Enter multiple value: ").split(",")]
print("Number of list is: ", x)
