循环印刷的整个范围

Question

我是Python的新手，学习了For Loops并编写了以下代码：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}!")我得到这个结果：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]!对于“我可以数更多”的部分，如何获取它以数字顺序列出范围：I can count more: 1! I can count more: 2!, etc.而不是打印行中的整个范围？

Answer 1

print(f"I can count more: {new_list}!")

应该

print(f"I can count more: {numbers}!")

因为new_list是整个列表，并且numbers是您for在中定义的变量for numbers in new_list

Answer 2

使用“数字”代替“ new_list”。并且不要在同一列表上一次又一次地迭代，因为new_list包含您在上一个循环中显示的相同项目。所以，您的代码应该是这样的，

for numbers in range(0, 4):

    print(f"I can count more: {numbers}!")
