Lecture-4 User Input & Type Casting in Python

User Input

Python allows for user input. That means we are able to ask the user for input. input()=To take input from user.

Example=

val=input("Message")

name=input("Enetr Yourname :")
print(name)

Formatting Output

name=input("Enetr Yourname :")
print("Good Evening {}".format(name))

val1=input("Enter val1:")
val2=input("Enter val2:")
sum=val1+val2
print(sum)

Type Casting

Type Casting is the method to convert the variable data type into a certain data type in order to the operation required to be performed by users.

Example=

val1=int(input("Enter val1:"))
val2=int(input("Enter val2:"))
sum=val1+val2
print(sum)

val1=(input("Enter val1:"))
val2=(input("Enter val2:"))
sum=int(val1) + int(val2)
print(sum)

Formatting Output

val1=(input("Enter val1:"))
val2=(input("Enter val2:"))
sum=int(val1) + int(val2)
print("sum of {} and {} is {}".format(val1,val2,sum))

1️⃣Write a program to calculate bill when rate and quantity is given by user.

💡 HINT: use formula bill = rate * quantity, take input for rate and quantity from user.

👁 Show Answer

val1=(input("Enter Rate:"))
