我在使用 python 中的字典时遇到问题

Question

I'm writing code with Python . I have defined a lot of dictionaries and a function. I use the dictionary in the function. The dictionary name is the parameter's in function. I want to get user input which dictionary to use but I don't know how to do this. I tried to get the name of the dictionary with the name in the code line below but it didn't

name=input()
bank("name") 
error is:
Traceback (most recent call last):
  File "............", line 47, in <module>
    banka("hesap")
  File "...................", line 18, in banka
    print("merhaba",hesap['ad'])
TypeError: string indices must be integers

Answer 1

It's this part of your code:

hesap['ad']

According to the error, hasep is a string, not a dictionary. So you can only put integers into the square brackets.

Answer 2

You could maybe do someting like this

dictionary1 = {}
dictionary2 = {}
user_input = input("Enter 'dictionary1' for dictionary 1 or enter 'dictionary2' for dictionary 2")
if user_input ==  "dictionary1":
    bank(user_input)

elif user_input == "dictionary2":
    bank(user_input)
else:
    print("unknown command")

Also for your code, when you used the bank function, you put the variable 'name' in speech marks. If you want to input the variable name in the function bank, dont add speech marks. :)

Answer 3

Maybe try doing this:

dict1={...}
dict2={...}

def bank(x):
     if x=="dict1":
         usedict=dict1
     elif x=="dict2":
         usedict=dict2
     else:
         print("No dictionary found with input given")
     ## write your program using usedict
x=input("enter which dictionary to use")
bank(x)

Remember, if you want to use the dictionary usedict outside the function as well, use global usedict inside the function
