Python looping and program restart if true

Question

Please help as I am a true beginner and would love to learn more. I am trying to learn more about looping so take a look at this code please.

# lets the user inp         


        

Answer 1

You could also make a variable called should_restart (or whatever you want to call it) and set it equal to True before the loop. Then set the loop to happen if should_restart is equal to True. Then you could say if the user inputs yes it continues but if the user answers no it sets should_restart equal to True

# decides whether to keep looping or not
should_restart = True
while should_restart == True:

    # lets the user input first number
    num1 = float(raw_input("Enter your first number  ---> "))

    # lets the user input second number
    num2 = float(raw_input("Enter your second number  ---> "))

    #the next four lines sets the basic mathematical equations
    addAns = num1+num2
    subAns = num1-num2
    mulAns = num1*num2
    divAns = num1/num2

    # ask the user to let the program know what equation to run with an 
    option of running them all
    operator = raw_input("What operator would you like to use(+,-,*,/ or ALL)")

    #these if and else statements are based on the input by the user.         
    Depending on the operator chosen it will print that equation.
    if operator == "+":
        print "the result of:\t " ,num1, "+" ,num2, "=" ,addAns,
    elif operator == "-":
        print "\nthe result of:\t " ,num1, "-" ,num2, "=" ,subAns,
    elif operator == "*":
        print "\nthe result of:\t " ,num1, "*" ,num2, "=" ,mulAns,
    elif operator == "/":
        print "\nthe result of:\t " ,num1, "/" ,num2, "=" ,divAns,
    elif operator == "ALL" or "all" or "All":
        print "the result of:\t " ,num1, "+" ,num2, "=" ,addAns,
        print "\nthe result of:\t " ,num1, "-" ,num2, "=" ,subAns,
        print "\nthe result of:\t " ,num1, "*" ,num2, "=" ,mulAns,
        print "\nthe result of:\t " ,num1, "/" ,num2, "=" ,divAns,
    answer = raw_input("Would you like to try again?(yes or no)")
    if answer == 'yes' or 'Yes':
        continue
    elif answer == 'no' or 'No':
        should_restart = False

Answer 2

you can try defining a function calc or what ever u want and write the whole code in that function and u can directly call that function whenever u need

def calc():
 your code

if answer == 'yes' or 'Yes':calc()
elif answer == 'no' or 'No':print "Thanks for using my calculator

UPDATED: You have to use a while loop like this:

while True:
    # lets the user input first number
    num1 = float(raw_input("Enter your first number  ---> "))

    # lets the user input second number
    num2 = float(raw_input("Enter your second number  ---> "))

    #the next four lines sets the basic mathematical equations
    addAns = num1+num2
    subAns = num1-num2
    mulAns = num1*num2
    divAns = num1/num2

    # ask the user to let the program know what equation to run with an 
    #option of running them all
    operator = raw_input("What operator would you like to use(+,-,*,/ or ALL)")

    #these if and else statements are based on the input by the user.         
    #Depending on the operator chosen it will print that equation.
    if operator == "+":
        print "the result of:\t " ,num1, "+" ,num2, "=" ,addAns,
    elif operator == "-":
        print "\nthe result of:\t " ,num1, "-" ,num2, "=" ,subAns,
    elif operator == "*":
        print "\nthe result of:\t " ,num1, "*" ,num2, "=" ,mulAns,
    elif operator == "/":
        print "\nthe result of:\t " ,num1, "/" ,num2, "=" ,divAns,
    elif operator == "ALL" or "all" or "All":
        print "the result of:\t " ,num1, "+" ,num2, "=" ,addAns,
        print "\nthe result of:\t " ,num1, "-" ,num2, "=" ,subAns,
        print "\nthe result of:\t " ,num1, "*" ,num2, "=" ,mulAns,
        print "\nthe result of:\t " ,num1, "/" ,num2, "=" ,divAns,

    answer = raw_input("Would you like to try again?(yes or no)")
    if answer == 'no': break
print  "Thanks for using my calculator!!!"
