如何將數組添加到此？

Question

from random import randint 
for i in range(5): 
    FN = (input("What is your name?")) 
    firstletter = FN[:1] 
    SN = [] 
    first3letters = SN[:3] 
    x = str(len(SN)) 
    sentence = str(randint(0,9))+(first3letters.lower())+(firstletter.upper()+(x)) 
    print(sentence) 

我需要創建一個數組，它將被打印出來，並由使用此代碼生成的5個用戶名組成。我會怎麼做？

在使用lower()和upper()之前，將firstletter和first3letters轉換爲字符串。

from random import randint 
for i in range(2): 
    FN = input("What is your name? ") 
    firstletter = ''.join(FN[:1]) 

    SN = 'bMwGermany' 
    first3letters = ''.join(SN[:3]) 
    x = str(len(SN)) 

    # sentence = str(randint(0,9))+(first3letters.lower())+(firstletter.upper()+(x)) 
    sentence = ''.join([str(randint(0, 9)), first3letters.lower(), firstletter.upper(), x]) 
    print(sentence) 

# Test 
$ python3 stackoverflow.py 
What is your name? hello 
1bmwH8 
What is your name? world 
9bmwW8 

注意，對於Python2，使用raw_input代替input。有關詳細說明，請參閱Python input() error - NameError: name '…' is not defined。
