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

Question

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])

Answer 1

a = {
    "a": [
        "***",
        "* *",
        "***",
        "* *",
        "* *",
    ],
    "b": [
        "** ",
        "* *",
        "** ",
        "* *",
        "** ",
    ]
}

string = "abab"

data = [a[char] for char in string]

# 5 because the "big letters" have 5 rows
for i in range(5):
    row = " ".join(d[i] for d in data)
    print(row)
