Code that changes the users input to lower case

There is a piece of code that changes anything the user inputs to lower case, how would I implement this into my code instead of using ["a" or "A"]?

def displaymenu():
    print("Weather station")
    print("Please enter the option you would like")
    optionchoice = input("Please enter A,B,C or D:")

    if optionchoice in ["a" or "A"]:
        print("The temperature will be displayed")
        time.sleep(1)
        optionA()

    elif optionchoice in ["b" or "B"]:
        print("The wind speed will be displayed")
        time.sleep(1)
        optionB()

    elif optionchoice in ["c" or "C"]:
        print("The day and time will be displayed")
        time.sleep(1)
        optionC()

    elif optionchoice in ["d" or "D"]:
        print("The Location will be displayed")
        time.sleep(1)
        optionD()

    else:
        print("Please type a valid input")
        displaymenu()

Using str.lower() method, you could make changes to your code like so:

def displaymenu():
    print("Weather station")
    print("Please enter the option you would like")

    optionchoice = input("Please enter A, B, C or D: ").lower() # Convert input to lowercase.

    if optionchoice == 'a':
        print("The temperature will be displayed")
        time.sleep(1)
        optionA()

    elif optionchoice == 'b':
        print("The wind speed will be displayed")
        time.sleep(1)
        optionB()

    elif optionchoice == 'c':
        print("The day and time will be displayed")
        time.sleep(1)
        optionC()

    elif optionchoice == 'd':
        print("The Location will be displayed")
        time.sleep(1)
        optionD()

    else:
        print("Please type a valid input")
        displaymenu()

If for some reason you want to stick with your version, validate the input like so:

if optionchoice in ['a', 'A']:

if you use python 2 you should use raw_input().lower().

Actually Python has a built in method:

For example:

string = "ABCDabcd123"
lowercase = string.lower()
print(lowercase)

will give you abcdabcd123 !

Try it out and find more about it here: https://www.tutorialspoint.com/python/string_lower.htm

Try something like this:

optionchoice = input("Please enter A,B,C or D:").lower()

This way you are forcing the input to the lowercase version of whatever the user types.
