"I'm not comfortable accepting donations for my work. Rather, I would like to encourage you to donate to a struggling family or a charity of your choosing."
He really said that.
Truly a bro we all need.

Fast way to make with modern python :
num1 = int(input("Enter 1st number: "))
num2 = int(input("Enter 2nd number: "))
calculate = input("Enter + or - or x or / : ")
match calculate:
case "+" :
print("The sum is :", num1 + num2)
case "-" :
print("The subtract is :", num1 - num2)
case "x" :
print("The product is :", num1 * num2)
case "/" :
print("The division is :", num1 / num2)

i’d personally prefer it goes like this
the 1st number, then the operation and then the second number.
it seems more user friendly, but thank you for the tutorial !

I never thought of being a coder until I saw your videos, thank you so muck

[twigginbarrys]

I just started watching your videos yesterday and I wish I had started a long time ago I am having too much fun.
operator = input("pick and operation (+, -, *, /) ")
if operator == "+":
num1 = float(input("what is the first number you would like to add to? "))
num2 = float(input("what is the second number you would like to add? "))
result = num1 + num2
print(f"{num1} plus {num2} equals {(round(result, 3))}")
elif operator == "-":
num1 = float(input("what is the first number you would like to subtract from? "))
num2 = float(input("what is the second number you would like to subtract by? "))
result = num1 - num2
print(f"{num1} minus {num2} equals {(round(result, 3))}")
elif operator == "*":
num1 = float(input("what is the first number you would like to multiply? "))
num2 = float(input("what is the second number you would like to multiply by? "))
result = num1 * num2
print(f"{num1} multiplied by {num2} equals {(round(result, 3))}")
elif operator == "/":
num1 = float(input("what is the first number you would like to divide? "))
num2 = float(input("what is the second number you would like to divide by? "))
result = num1 / num2
print(f"{num1} divided by {num2} equals {(round(result, 3))}")
else:
print("INVALID SELECTION! Please try again")

This course has been incredible! Thank you!!

[zahranurrohma]

Thank you for the lesson,
this is what I made today :D

operator = input("Enter an operator (+ - * /): ")

valid_operator = list ["+", "-", "*", "/"]
if operator not in valid_operator:
print(f"{operator} is not a valid operator")
exit()

num1 = float(input("Enter the 1st number: "))
num2 = float(input("Enter the 2nd number: "))

if operator == "+":
result = num1 + num2
print(round(result, 3))
elif operator == "-":
result = num1 - num2
print(round(result, 3))
elif operator == "*":
result = num1 * num2
print(round(result, 3))
elif operator == "/":
result = num1 / num2
print(round(result, 3))
else:
print("")

Thank U brother for this Course, I have no words to explain it, btw Your voice is so Cool! 💗

import math
print("division (-)")
print("Addition (+)")
print("Multiplication (*)")
print("Division (/)")
print("Power (**)")
print("Square roots (sqr)")

operator = input("Enter one of the operators above: ")

if operator == "-":
x = float(input("Enter first value: "))
y = float(input("Enter a second value: "))
minus = x - y
print(f"It is equal: {minus} ")
elif operator == "*":
x = float(input("Enter first value: "))
y = float(input("Enter a second value: "))
times = x * y
print(f"It is equal: {times} ")
elif operator == "/":
x = float(input("Enter first value: "))
y = float(input("Enter a second value: "))
if y == 0 :
print("You can't divide by zero!!!")
else:
times = x / y
print(f"It is equal: {times} ")
elif operator == "**":
x = float(input("Enter first value: "))
y = float(input("Enter power value: "))
power = pow(x, y)
print(f"It is equal: {power} ")
elif operator == "sqr":
x = float(input("Enter value you want to square: "))
sqr = math.sqrt(x)
print(f"It is equal: {sqr} ")
else:
print("Enter a proper operator you dummy!!")

a=input("enter your first numper ")

a1=input("enter your second numper ")

s1=int(a)+int(a1)
s2=int(a)/int(a1)
s3=int(a)*int(a1)
s4=int(a)-int(a)

calcul=input("calcule +, /, *, -")

if (calcul)=="+": print(s1)
if (calcul)=="/": print(s2)
if (calcul)=="*": print(s3)
if (calcul)=="-": print(s4)

I coded my self and now i know that there is an elseif command
😊

[julkarnayenshish]

I predict, this channel will become more popular than cs50 or freecodecamp or any other coding channels in youtube if this kind of content continues to be uploaded.

[gaddafisuleiman]

So happy 😁 you uploaded a video.
😅 I've been waiting....

[thosan]

Can you teach us how to code a calculator program that can calculate the math expression from an input string like 2 * (9 - 16/4), I will very appreciate it sir.

[hcuznrs]

a=int(input())
if a%4==0:
print("kabisa")
else:
print("kabisa emas")

[vaggelisgeorgiou]

I just picked up coding and I absolutely love your tutorials, thank you Bro for all the effort you put in!!
I have a question. Couldn't we have made only one print( ) in the end of all the if elif else? Something like print(f" {num1} {operator} {num2} = {result} ")
Wouldn't that work instead of having many print( ) statements for all the steps?

[srcafezin]

The tutorial is good, but you also can do: print(eval(input("enter ")))

[Priceygames]

Ive learned C++ from your videos, Python is just so easy

[Friday_]

That was fun! I was trying to get a statement to print, where if the user input an invalid operator it would print it before asking for num1 & num2. Got to find out what command that is though.
