How to find and change a variable's value through input

I’m trying to make like an ON/OFF switch. Once a variable name is entered I want it going from ‘off’ to ‘on’. There’s a lot of variables so code looks really messy if I type ‘varx = ‘on’‘ for every input

VAR1 = 'off'
VAR2 = 'off'
VAR3 = 'off'

while True:
    findvar = input('Which variable do you want to turn on?: )
    >> finds the variable and changes value to 'on'

I’m trying to get it so when I type var1 on the input, VAR1 goes from ‘off‘ to ‘on‘

I tried dictionary but I haven’t found to use dictionary to change variables.

Thanks!

>Solution :

Use a dictionary.

d = {
    'VAR1': 'off',
    'VAR2': 'off',
}

name = input('What variable do you want to turn on? ')
d[name] = 'on'
