python脚本-计算脚本中的代码行数

我正在raspberry pi上运行python脚本，我只是想知道是否有任何命令可以用来计算脚本中的行数

关于

您可以先读取文件，然后计算所有既不是空的也不是以符号或或开头的行（所有这些都表示注释）：

这将打印出：

Significant line: import os
Significant line: import re
Significant line: SINGLE_LINE_COMMENT_DELIMITER = "#"
Significant line: MULTILINE_COMMENT_DELIMITER_PATTERN = re.compile("['\"]{3}")
Significant line: class SignficantLineParser(object):
Significant line:   def __init__(self):
Significant line:       self.in_comment_section = False
Significant line:   def parse(self, line):
Significant line:       line = line.strip()
Significant line:       if self.in_comment_section:
Significant line:           if line.startswith(SINGLE_LINE_COMMENT_DELIMITER):
Significant line:               return False
Significant line:           else:
Significant line:               if MULTILINE_COMMENT_DELIMITER_PATTERN.match(line):
Significant line:                   self.in_comment_section = False             
Significant line:       elif line:
Significant line:           if line.startswith(SINGLE_LINE_COMMENT_DELIMITER):
Significant line:               return False
Significant line:           else:
Significant line:               if MULTILINE_COMMENT_DELIMITER_PATTERN.match(line):
Significant line:                   self.in_comment_section = True
Significant line:                   return False
Significant line:               else:
Significant line:                   return True
Significant line:       else:
Significant line:           return False
Significant line: script_path = os.path.realpath(__file__)
Significant line: with open(script_path, 'r') as inf:
Significant line:   parser = SignficantLineParser()
Significant line:   significant_lines = 0
Significant line:   for line in inf:
Significant line:           if parser.parse(line):
Significant line:               significant_lines += 1
Significant line:               print("Significant line: " + line, end="")
Significant line: print("\n\nSignificant line count: %d" % significant_lines)

Significant line count: 35

然后，您可以读取文件，计算所有既不是空的也不是以

符号开头的行，或

'

或

'

开头的行（所有行都表示注释）：

这将打印出：

Significant line: import os
Significant line: import re
Significant line: SINGLE_LINE_COMMENT_DELIMITER = "#"
Significant line: MULTILINE_COMMENT_DELIMITER_PATTERN = re.compile("['\"]{3}")

Significant line:   def __init__(self):
Significant line:       self.in_comment_section = False
Significant line:   def parse(self, line):
Significant line:       line = line.strip()
Significant line:       if self.in_comment_section:
Significant line:           if line.startswith(SINGLE_LINE_COMMENT_DELIMITER):
Significant line:               return False
Significant line:           else:
Significant line:               if MULTILINE_COMMENT_DELIMITER_PATTERN.match(line):
Significant line:                   self.in_comment_section = False             
Significant line:       elif line:
Significant line:           if line.startswith(SINGLE_LINE_COMMENT_DELIMITER):
Significant line:               return False
Significant line:           else:
Significant line:               if MULTILINE_COMMENT_DELIMITER_PATTERN.match(line):
Significant line:                   self.in_comment_section = True
Significant line:                   return False
Significant line:               else:
Significant line:                   return True
Significant line:       else:

Significant line: script_path = os.path.realpath(__file__)
Significant line: with open(script_path, 'r') as inf:

Significant line count: 35
