python - 在python循环中迭代float变量时出错

Question

我使用score将变量设置为 float 列表marks，但由于Code

for score in range(marks):

错误为:

'float' object cannot be interpreted as an integer

Answer 1

自己遍历您的花车

for score in marks:
    # score is a float now

或使用他们的索引

for i in range(len(marks)):
    # do something with marks[i]
    score = marks[i]

或者如果您同时需要索引和值

for i, score in enumerate(marks):
    # i is the index, score is the float
