为什么在函数外时pylint需要大写的变量名？ 

为什么pylint在函数外部时接受大写变量,而在函数内部拒绝它们？相反,为什么pylint拒绝camelCase ouside函数并在函数内部接受它？

我刚刚安装了pylint(版本2.2.2)来检查我的Python3.一定错过了某些东西.我相关的Python /软件包版本是：

1. pylint 2.2.2
2. astroid 2.1.0
3. Python 3.6.7 | packaged by conda-forge | (default,Nov 20 2018,18:20:05)
4. [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.37)]

考虑下面的代码(test_1),其中我使用camelCase和大写的变量命名.大写的变量被接受(为什么？)而骆驼的情况被拒绝(我想是因为代码没有包装到函数中).

1. '''
2. Nothing important
3. '''
5. fileHandler = open("afile.txt")
7. for line in fileHandler:
8. Token = line.split("\t")
9. Part_1 = Token[0]
10. print(Part_1)

哪个调用pylint：

1. $pylint --py3k --enable=all test_1.py
2. ************* Module test_1
3. test_1.py:5:0: C0103: Constant name "fileHandler" doesn't conform to UPPER_CASE naming style (invalid-name)
5. ------------------------------------------------------------------
6. Your code has been rated at 8.00/10 (previous run: 8.00/10,+0.00)

现在,如果我将所有内容都放入一个函数中(test_2).

1. '''
2. Nothing important
3. '''
5. def foo():
6. fileHandler = open("afile.txt")
8. for line in fileHandler:
9. Token = line.split("\t")
10. Part_1 = Token[0]
11. print(Part_1)
13. if __name__ == '__main__':
14. foo()

然后将大写变量检测为不合规(这是我所期望的)：

1. $pylint --py3k --enable=all test_2.py
2. ************* Module test_2
3. test_2.py:5:0: C0102: Black listed name "foo" (blacklisted-name)
4. test_2.py:5:0: C0111: Missing function docstring (missing-docstring)
5. test_2.py:6:4: C0103: Variable name "fileHandler" doesn't conform to snake_case naming style (invalid-name)
6. test_2.py:9:8: C0103: Variable name "Token" doesn't conform to snake_case naming style (invalid-name)
7. test_2.py:10:8: C0103: Variable name "Part_1" doesn't conform to snake_case naming style (invalid-name)
9. ------------------------------------------------------------------
10. Your code has been rated at 3.75/10 (previous run: 3.75/10,+0.00)

我有一些不清楚的地方…欢迎澄清…
