Ask about python import through if/else

Question

I am learning basic python. I use the basics of python for my java homework and built a menu with 3 options. 1st option is simple equation. 2nd option is quadratic equation. 3rd option is calculate electricity bill

print("1. simple equation")
print("2.  quadratic equation")
print("3. calculate electricity bill")
print("Choose")
x=int(input());
if(x>3):
    print("no update")
elif(x==1):
    import lab3_1
elif(x==2):
    import lab3_2
else:
    import lab3_3

my question is : Do we have another way to build a menu without using if else? Why import doesn't work in python's switch case?

What are you trying to accomplish here? Python does not have `switch` statement — Ach113, Mar 13 '20 at 09:49
Make use of dict (which is Python's equivalent of Java's Map) and map input with desired functions. Which is way better than switch/case — curiouscupcake, Mar 13 '20 at 09:49

Try below to import the required module.

mod_dict={1:'lab3_1', 2:'lab3_2' , 3:'lab3_3'
required_module=__import__(mod_dict[x])

Use required_module.operation() as your wish. For eg, required_module.add(), here the module will be imported under key word required_module.
