问题描述
我知道，存在用于解析python代码的库，但是，为了学习它们如何解析错误，我正在创建一个脚本，该脚本仅检查文件中是否存在6个Pep8错误以供参考。
这是我当前的6个Pep8函数的外观（如果发现问题，它们会在问题列表中附加一个问题）
"""
[S001] Line is longer than 79 characters
[S002] Indentation is not a multiple of four
[S003] Unnecessary semicolon after a statement (note,semicolons are admissible in comments)
[S004] At least two spaces before inline comments required
[S005] Todo found (only in comments; the case does not matter)
[S006] More than two blank lines used before this line (must be output for the first non-empty line)
"""
def S001(self,ln_num: int,line: str):
if len(line) > 79:
self.issues.append(f"Line {ln_num}: S001 Too Long")
def S002(self,line: str):
indentation_length = len(line) - len(line.lstrip())
if indentation_length % 4 != 0:
self.issues.append(f"Line {ln_num}: S002 Indentation is not a multiple of four")
def S003(self,line: str):
regex1 = re.compile("(.*)((;(\s)*#)|(;$))")
regex2 = re.compile("#.*;")
if regex1.search(line) and not regex2.search(line):
self.issues.append(f"Line {ln_num}: S003 Unnecessary semicolon")
def S004(self,line: str):
regex = re.compile("(([^ ]{2})|(\s[^ ])|([^ ]\s))#")
if regex.search(line):
self.issues.append(f"Line {ln_num}: S004 At least two spaces before inline comments required")
def S005(self,line: str):
regex = re.compile("#(.*)todo",flags=re.IGnorECASE)
if regex.search(line):
self.issues.append(f"Line {ln_num}: S005 Todo found")
def S006(self,line: str):
if self.code[ln_num-4:ln_num-1] == ['','',''] and line != "":
self.issues.append(f"Line {ln_num}: S006 More than two blank lines used before this line")
测试用例：
""" Test case 1 """
print('What\'s your name?') # reading an input
name = input();
print(f'Hello,{name}'); # here is an obvIoUs comment: this prints greeting with a name
very_big_number = 11_000_000_000_000_000_000_000_000_000_000_000_000_000_000_000
print(very_big_number)
def some_fun():
print('NO Todo HERE;;')
pass; # Todo something

""" Test Case 2 """
print('hello')
print('hello');
print('hello');;;
print('hello'); # hello
# hello hello hello;
greeting = 'hello;'
print('hello') # ;
""" END """
""" Test Case 3 """
print('hello')
print('hello') # Todo
print('hello') # Todo # Todo
# todo
# Todo just do it
print('todo')
print('Todo Todo')
todo()
todo = 'todo'
""" END """
""" Test Case 4 """
print("hello")
print("bye")
print("check")
""" END """
""" Test Case 5 """
print('hello!')
# just a comment
print('hello!') #
print('hello!') # hello
print('hello!') # hello
print('hello!')# hello
""" END """
测试用例1的预期输出：
Line 1: S004 At least two spaces before inline comment required
Line 2: S003 Unnecessary semicolon
Line 3: S001 Too long
Line 3: S003 Unnecessary semicolon
Line 6: S001 Too long
Line 11: S006 More than two blank lines used before this line
Line 13: S003 Unnecessary semicolon
Line 13: S004 At least two spaces before inline comment required
Line 13: S005 Todo found
我知道我的代码不是最优的，并且不能满足所有极端情况，但是我想知道它们如何正确解析错误的想法。由于我个人不喜欢我的答案，因此我想对如何分析错误进行改进或更好的主意。
