I have a question about how to call the variable name created through Python operation.

I would like to ask you how you can call the variable name obtained through the calculation result.

For example,

year_list = [2020, 2021, 2022]
for i in year_list :  
   name = str(i) + 'data'
   print(name)

2020data 
2021data
2022data

--- Description (question) ---

You want to create a dictionary with the result value obtained through the for statement above as a variable name. (Question 1 part)

ex) 2020data = {}, 2021data= {}, 2022data= {}

And when you run another operation in the future, you want to call up the variable name you want (ex) 2020data) and proceed with another operation.

Here's the question!

data_holder = dict()
while True:
    k = input ("data name:")
    if k == "end":
        break
    data = input ("data to store:")
    data_holder[k] = data

while True:
    k = input ("What data do you want to see?"")
    if not k in data_holder:
        No data is saved under the name print(f"{k}.")
        continue
    print(f"data {k} is {data_holder[k]}.")
