for i in xrange 报错

在Python 3中,`xrange()`已经被移除了。你可以使用`range()`函数代替。如果你是从Python 2迁移到Python 3,你可以使用`range()`函数来替换`xrange()`函数。
例如,如果你原来的代码是:
```
for i in xrange(10):
print(i)
```
你可以将其改为:
```
for i in range(10):
print(i)
```
这样就可以避免`xrange()`函数的错误了。

for i in xrange()
It seems like you are trying to use the `xrange()` function in Python. However, the `xrange()` function is only available in Python 2.x, and it has been replaced by the `range()` function in Python 3.x.
The `range()` function generates a sequence of numbers, similar to `xrange()`. Here's an example of how to use it:
```python
for i in range(10):
print(i)
```
This loop will iterate over the numbers from 0 to 9 and print each number on a separate line. You can specify the start, stop, and step parameters in the `range()` function if you need a different range of numbers.
If you are using Python 2.x, you can continue to use `xrange()` in the same way as in your code.
for i in xrange(len(nums)):
It seems like you are trying to iterate over a sequence of numbers using a `for` loop in Python. However, the use of `xrange` suggests that you might be using Python 2.x instead of Python 3.x.
In Python 2.x, the `xrange` function generates numbers on-the-fly, which is more memory-efficient for large ranges. In Python 3.x, the equivalent function is `range`.
Here's an example of how you can use a `for` loop with `xrange` in Python 2.x to iterate over a sequence of numbers:
```python
nums = [1, 2, 3, 4, 5]
for i in xrange(len(nums)):
print(nums[i])
```
This code will iterate over the indices of the `nums` list and print each element.
