我是Python的新手，學習了For Loops并編寫了以下代碼：cars = [1, 2, 3, 4]trucks = ['red', 'blue', 'green', 'white']for numbers in cars: print (f"I can count: {numbers}")for colors in trucks: print(f"I can list colors: {colors}")new_list = []for numbers in range(0, 4): new_list.append(numbers)for numbers in new_list: print(f"I can count more: {new_list}!")我得到這個結果：I can count: 1I can count: 2I can count: 3I can count: 4I can list colors: redI can list colors: blueI can list colors: greenI can list colors: whiteI can count more: [0, 1, 2, 3]!I can count more: [0, 1, 2, 3]!I can count more: [0, 1, 2, 3]!I can count more: [0, 1, 2, 3]!對于“我可以數更多”的部分，如何獲取它以數字順序列出范圍：I can count more: 1! I can count more: 2!, etc.而不是打印行中的整個范圍？

print(f"I can count more: {new_list}!")應該
print(f"I can count more: {numbers}!")因為new_list是整個列表，并且numbers是您for在中定義的變量for numbers in new_list

使用“數字”代替“ new_list”。并且不要在同一列表上一次又一次地迭代，因為new_list包含您在上一個循環中顯示的相同項目。所以，您的代碼應該是這樣的，
for numbers in range(0, 4):
print(f"I can count more: {numbers}!")
