我有這個，但不知道這是否是正確的代碼使用或放置在哪里。我需要幫助按字母對聯系人串列進行排序并添加列印代碼，以便像列印機一樣列印。有什么幫助嗎？謝謝
strs = ['aa', 'BB', 'zz', 'CC']
print(sorted(strs)) ## ['BB', 'CC', 'aa', 'zz'] (case sensitive)
print(sorted(strs, reverse=True)) ## ['zz', 'aa', 'CC', 'BB']
我不擅長編碼，任何幫助都很好，分類和列印到列印件會很棒。謝謝你的幫助。
uj5u.com熱心網友回復：
你可以這樣寫 display_contact() 。
def display_contact():
for name, number in sorted((k,v) for k, v in contact.items()):
print(f'Name={name}, number={number}')
您可能希望根據所需的排序順序將關鍵引數傳遞給sorted() 。
請注意，函式名稱用詞不當，因為它會列印所有聯系人
