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。

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 Python code snippet that iterates through the elements in the sequence "vals". The variable "i" takes on the value of each element in the sequence, one at a time, and the code inside the loop is executed for each element.
