A simple python calculator

Mohammad Alsuwaidi — Wed, 22 Dec 2021 07:02:58 +0000

i made a simple python calculator using while loop

# simple calculator


def add(x, y):
    return x + y


def sub(x, y):
    return x - y


def mul(x, y):
    return x * y


def div(x, y):
    return x / y


print("Select operation.")
print("( + )for Add")
print("( - ) for Subtract")
print("( * ) for Multiply")
print("( / ) for Divide")

while True:
    choice = raw_input("Enter the operation: ")
    if choice in ('+', '-', '/', '*'):
        num1 = float(input("Enter first number: "))
        num2 = float(input("Enter second number: "))

        if choice == '+':
            print num1, "+", num2, "=", (add(num1, num2))
        elif choice == '-':
            print num1, "-", num2, "=", (sub(num1, num2))
        elif choice == "*":
            print num1, "*", num2, "=", (mul(num1, num2))
        elif choice == '/':
            print num1, "/", num2, "=", (div(num1, num2))
    n12 = raw_input("Do u want to calculate another equation (y/n): ")
    if n12 == 'y' or n12 == 'Y':
        continue
    else:
        break

Python bmi calcultor

Mohammad Alsuwaidi — Wed, 15 Dec 2021 10:29:55 +0000

wrote a quick bmi calculator for imperial and metric it might not be perfect but i wanna know how can i make it better

m_or_i = int(input("Enter 1 for metric and 2 for imperial: "))

if m_or_i == 1:
    h1 = float(input("Enter your height in cm: "))
    h = h1 / 100
    w = float(input("Enter your weight in kgs: "))
    an = w / h ** 2
    if an < 18.4:
        print"Your bmi is:", (round(an, 1)), "which means you are under weight"
    elif 18.5 <= an <= 24.9:
        print"Your bmi is:", (round(an, 1)), "which means you are normal weight"
    elif 25 <= an <= 29.9:
        print"Your bmi is:", (round(an, 1)), "which means you are over weight"
    elif 30 <= an <= 34.9:
        print"Your bmi is:", (round(an, 1)), "which means you are obese class 1"
    elif 35 <= an <= 39.9:
        print"Your bmi is:", (round(an, 1)), "which means you are obese class 2"
    elif an >= 40:
        print"Your bmi is:", (round(an, 1)), "which means you are obese class 3"

elif m_or_i == 2:
    h1 = float(input("Enter your height in feet: "))
    h2 = float(input("Enter the inches: "))
    h = h1 * 12 + h2
    w = float(input("Enter your weight in pounds: "))
    an = w * 703 / h ** 2
    if an < 18.4:
        print"Your bmi is:", (round(an, 1)), "which means you are under weight"
    elif 18.5 <= an <= 24.9:
        print"Your bmi is:", (round(an, 1)), "which means you are normal weight"
    elif 25 <= an <= 29.9:
        print"Your bmi is:", (round(an, 1)), "which means you are over weight"
    elif 30 <= an <= 34.9:
        print"Your bmi is:", (round(an, 1)), "which means you are obese class 1"
    elif 35 <= an <= 39.9:
        print"Your bmi is:", (round(an, 1)), "which means you are obese class 2"
    elif an >= 40:
        print"Your bmi is:", (round(an, 1)), "which means you are obese class 3"

Python program that Counts down time

Mohammad Alsuwaidi — Mon, 13 Dec 2021 11:04:18 +0000

I Made a program that counts down the time and at the end makes a sound when the times up



import sys
import time
import os

a = int(input("Enter the amount of seconds: "))
if a >= 1:
    for i in range(a - 1, 0, -1):
        print i, "seconds"
        time.sleep(1)
    print"Time is up"
    os.system('say "Time is up."')
else:
    sys.exit()

Fast text to speech python

Mohammad Alsuwaidi — Mon, 13 Dec 2021 10:59:59 +0000

i've written a code that can turn text into speech using the os system in python

it's a simple 3 line code



# Text to speech
import os

text = raw_input("ENTER ANYTHING: ")

os.system("say %s" % text)
