for i in vals

It seems like the code you provided is incomplete. The "vals" variable should be defined beforehand and there should be a colon at the end of the line. Could you provide more context or code for me to better understand your question?

for i in vals:

This is a code snippet in Python that loops through a sequence of values stored in the variable "vals". The loop variable "i" takes on each value in "vals" one by one, and the indented code block below the loop is executed for each value of "i".

for i in vals是什么意思

这是一个Python的for循环语句，其中`vals`是一个可迭代对象，可以是列表、元组、集合或字典等。循环会遍历`vals`中的每个元素，并将每个元素赋值给变量`i`，然后执行循环体中的代码。例如：

vals = [1, 2, 3, 4, 5]
for i in vals:
    print(i)

输出结果为：

1
2
3
4
5

在每次循环中，变量`i`都会被赋值为`vals`中的下一个元素，直到遍历完所有元素为止。
