User Input in Python

Type Conversion

Float to Integer

# Convert into integer 
a = 5.25 
# Check of `a` type before conversion
type(a)
# Conversion
int_a = int(a)
# Check of `a` type after conversion
type(int_a) 

Integer to Float

# Convert into float 
b = 10 
# Check of `b` type before conversion
type(b)
# Conversion
float_b = float(b)
# Check of `b` type after conversion
type(float_b)

Integer to String

# Convert into string  
c = 20
# Check of `c` type before conversion
type(c) 
# Conversion
str_c = str(c)
# Check of `c` type after conversion
type(str_c)

String to Integer

# Convert into integer or float 
d = '20'
# Check of `d` type before conversion
type(d) 
# Conversion
int_d = int(d) 
# Check of `d` type after conversion
type(int_d)

Single Input–Without Message

# Take input from user without message 
input()
# Take input and store it to a variable 
num = input() 
print(num)
# Check your input type 
type(num)
# Convert your input
num2 = int(input())
num3 = float(input())
type(num3)
type(num2)

Single Input–With Message

# Take an input with message 
X = int(input("Enter an integer: "))
type(X)
# Check your input type 
# Convert your input

Put it Together

A = int(input("Enter an integer: "))

Examples

\begin{example} Write a Python Program to Add Two Integers \end{example}

# Write your solution here! 
num1 = int(input("Enter your first number: ")) 
num2 = int(input("Enter your second number: "))

total = num1 + num2
print("Total = ", total)
Enter your first number: 10
Enter your second number: 20
Total =  30

\begin{example} Write a Python Program to Multiply Two Floating Point Numbers \end{example}

# Write your solution here! 
num3 = float(input("Enter your first float: "))
num4 = float(input("Enter your second float: "))

total2 = num3 + num4 
print("Total = ", total2) 
Enter your first float: 10
Enter your second float: 20
Total =  30.0
