How do I make inputted letters as big letters using asterisk?

For example i inputted "ABC"

The output should be:

*** **  ***
* * * * *
*** **  *
* * * * *
* * **  ***

I only tried the letter A but it results an error.
Can someone help me do it in plain python without any modules

text = input("Enter my text: ").split()

A = [3, [1,0,1], 3, [1,0,1], [1,0,1]]

for i in range(text+1):
    if text[i] == 'A':
        print("*" * A[i])

>Solution :

That representation seems inconsistent, if you wanted to use a matrix to represent which elements are asterisks I’d suggest

A = [[1,1,1], [1,0,1], [1,1,1], [1,0,1], [1,0,1]]

Then you can loop over each row and print out either an asterisk or whitespace as appropriate

for row in A:
    print(''.join('*' if s == 1 else ' ' for s in row))
