Python字符串对象不支持错误

Question

我正在学习python，当我在做这个练习的时候...

student_scores = input("Input a list of student scores here ")

for n in range(0, len(student_scores)):
    student_scores[n] = int(student_scores[n])
print(student_scores)

highest_score = max(student_scores)
print(highest_score)


**i got the below error:** 
 line 5, in <module>
    student_scores[n] = int(student_scores[n])
TypeError: 'str' object does not support item assignment

Answer 1

就像错误说你不能给一个项目分配一个字符串一样。所以我想您要找的是函数split()。现在假设用户输入10个由空格分割的数字，split()将把它们变成一个字符串列表。然后您可以遍历每个字符串并将它们转换为int。

student_scores = input("Input a list of student scores here ")
student_scores=student_scores.split()
for n in range(0, len(student_scores)): 
    student_scores[n] = int(student_scores[n]) 
    print(student_scores)

highest_score = max(student_scores) 
print(highest_score)

下面是使用列表理解的代码的一行。它看起来很酷所以我把它放在这里。

x = max([int(num) for num in input("Input a list of student scores here ").split()])
