multiple entry labels in tkinter

I am a beginning (emphasis) programmer, and I am creating a study GUI application. I want to create multiple Entry fields for terms, and definitions. To create one Entry box, the code ( I believe) would be:

term = StringVar()
term1 = Entry(root, textvariable = term)
term1.grid(row=1, column=1)

My goal is to be able to prompt the user asking how many terms they want. My question is what loop would I have to run to automatically create a column of entry fields, specific to the number the user entered?

Assume you have got the user input x, an integer.

for i in range(x):
    Entry(root, textvariable=StringVar()).grid(row=1, column=i+1)

But unfortunately you can not get the value of the entries then. So we can take two lists.

variables = []
entries = []
for i in range(x):
    va = StringVar()
    en = Entry(root, textvariable=va)
    en.grid(row=1, column=i+1)
    variables.append(va)
    entries.append(en)

In this case, you can access the entry and variable then using the lists.

Then you may want names, for example, entry1, entry2, entry3, within the loop. This relates dynamically variable creation which can not be accessed in Python. There is a hack way using exec or __dict__, but it is not recommended. Just use the list or dict.
