# CBSE Class 11: Python Fundamentals 7

Question:1
Write a python script to take input for two numbers calculate and print their sum?
Sol:

```a=int(input("Enter 1st no "))
b=int(input("Enter 2nd no "))
s=a+b
print("1st no = ",a)
print("2nd no = ",b)
print("Sum = ",s)```

Output:

```Enter 1st no 10
Enter 2nd no 20
1st no =  10
2nd no =  20
Sum =  30
>>> ```

Question:2
Write a python script to take input for a number calculate and print its square?
Sol:

```a=int(input("Enter any no "))
b=a*a
print("Number ",a)
print("Square ",b)```

Output:

```Enter any no 5
Number  5
Square  25
>>> ```

Question:3
Write a python script to take input for a number calculate and print its cube?
Sol:

```a=int(input("Enter any no "))
b=a*a*a
print("Number ",a)
print("Cube ",b)```

Output:

```Enter any no 5
Number  5
Cube  125
>>> ```

Question:4
Write a python script to take input for two numbers to calculate and print their difference?
Sol:

```a=int(input("Enter 1st no "))
b=int(input("Enter 2nd no "))
d=a-b
print("1st no = ",a)
print("2nd no = ",b)
print("Difference = ",d)```

Output:

```Enter 1st no 10
Enter 2nd no 20
1st no =  10
2nd no =  20
Difference =  -10
>>> ```
