Collecting user input

input([prompt]) Accepting user input

prompt: (optional) String ( message ) to be shown to user

By default all inputs are of String data type.

Getting user input in Python & printing output after converting into integer by using int() function

Displaying input box to accept user inputs

x1=input("Enter first number: ")
x2=input("Enter second number: ")
print("Total :",x1+x2)

Output

Enter first number: 3
Enter second number: 4
Total : 34

Why the output is not equal to 7 with input of 3 and 4 as input numbers ?

As all user inputs are string data type ( by default ) , we have to convert the type by using int()

x1=int(input("Enter first number: "))
x2=int(input("Enter second number: "))
print("Total :",x1+x2)

Output

Enter first number: 3
Enter second number: 4
Total : 7

Float input

Used float() to convert string to float data type.

x1=float(input("Interest Rate is : "))
print ("interest rate ",x1)

Output

Interest Rate is : 5.6
interest rate  5.6

Use one input box and a for loop to ask user to enter three numbers, display the sum of three input numbers.

sum=0
for i in range(3):
    x1=int(input('Enter a number'))
    sum=sum+x1
print("Sum : ", sum)
