When i try to calculate (square) of number, (Enter first number) is executed first.

-----------------------------------------------------------------------------------------------------------------

# Calculator
def square():
number=int(input('Enter the number:'))
squ=(number*number)
print(squ)

2.Subtraction
3.Multiplication
4.Division
5.Square''')
option=input('Enter the option:')

num1=int(input('Enter the first number:'))
num2=int(input('Enter the second number:'))

if option == '1':
print('{} + {} = '.format(num1,num2))
print (num1+num2)
elif option == '2':
print('{} - {} = '.format(num1,num2))
print (num1_num2)
elif option == '3':
print('{} * {} = '.format(num1,num2))
print (num1*num2)
elif option == '4':
print('{} / {} = '.format(num1,num2))
print (num1/num2)
elif option =='5':
square()
else:
exit()

square()

Hi... just went through your question. The code written below will solve your issue:-

option = input('''
Enter the Serial Number of the
operation you want to perform''')

if option == "1":
elif option == "2":
subtraction()
elif option == "3":
multiplication()
elif option == "4":
division()
elif option == "5":
square()
else:
print("The operation you entered is not listed above")

num1 = int(input("Enter 1st number: "))
num2 = int(input("Enter 2nd number: "))
ans = num1 + num2
print("{} is the sum".format(ans))

def subtraction():
num1 = int(input("Enter 1st number: "))
num2 = int(input("Enter 2nd number: "))
ans = num1 - num2
print("{} is the diffrence".format(ans))

def multiplication():
num1 = int(input("Enter 1st number: "))
num2 = int(input("Enter 2nd number: "))
ans = num1 * num2
print("{} is the product".format(ans))

def division():
num1 = int(input("Enter 1st number: "))
num2 = int(input("Enter 2nd number: "))
ans = num1 / num2
print("{} is the quotient".format(ans))

def square():
num = int(input("Enter the number you want to sqaure: "))
ans = num ** 2
print("{} is the square of {}".format(ans, num))

print('''
2. Subtraction
3. Multiplication
4. Division
5. Square
''')

I hope you will be satisfied
