python create calculator code example
Example 1: python calculator
num_one = int(input("Enter 1st number: "))
op = input("Enter operator: ")
num_two = int(input("Enter 2nd number: "))
if op == "+":
print(num_one + num_two)
elif op == "-":
print(num_one - num_two)
elif op == "*" or op == "x":
print(num_one * num_two)
elif op == "/":
print(num_one / num_two)
Example 2: calculator in python
from replit import clear
def add(n1, n2):
return n1 + n2
def subtract(n1, n2):
return n1 - n2
def multiply(n1, n2):
return n1 * n2
def divide(n1, n2):
return n1 / n2
operations = {
"+": add,
"-": subtract,
"*": multiply,
"/": divide
}
def calculator():
print(logo)
num1 = float(input("What's the first number?: "))
for symbol in operations:
print(symbol)
should_continue = True
while should_continue:
operation_symbol = input("Pick an operation: ")
num2 = float(input("What's the next number?: "))
calculation_function = operations[operation_symbol]
answer = calculation_function(num1, num2)
print(f"{num1} {operation_symbol} {num2} = {answer}")
if input(f"Type 'y' to continue calculating with {answer}, or type 'n' to start a new calculation: ") == 'y':
num1 = answer
else:
