python统计指定目录内文件的代码行数
python统计指定目录内文件的代码行数,程序实现统计指定目录内各个python文件的代码总行数,注释行数,空行数,并算出所占百分比
这符合一些公司的小需求,实际代码量的统计工作
效果如图
代码如下:
#coding:utf-8 import os,re #代码所在目录 FILE_PATH = './' def analyze_code(codefilesource): ''' 打开一个py文件,统计其中的代码行数,包括空行和注释 返回含该文件总行数,注释行数,空行数的列表 :param codefilesource: :return: ''' total_line = 0 comment_line = 0 blank_line = 0 with open(codefilesource,encoding='gb18030',errors='ignore') as f: lines = f.readlines() total_line = len(lines) line_index = 0 #遍历每一行 while line_index < total_line: line = lines[line_index] #检查是否为注释 if line.startswith("#"): comment_line += 1 elif re.match("\s*'''",line) is not None: comment_line += 1 while re.match(".*'''$",line) is None: line = lines[line_index] comment_line += 1 line_index += 1 #检查是否为空行 elif line =='\n': blank_line += 1 line_index += 1 print("在%s中:"%codefilesource) print("代码行数:",total_line) print("注释行数:",comment_line,"占%0.2f%%"%(comment_line*100/total_line)) print("空行数:", blank_line, "占%0.2f%%"%(blank_line * 100 / total_line)) return [total_line,comment_line,blank_line] def run(FILE_PATH): os.chdir(FILE_PATH) #遍历py文件 total_lines = 0 total_comment_lines = 0 total_blank_lines = 0 for i in os.listdir(os.getcwd()): if os.path.splitext(i)[1] == '.py': line = analyze_code(i) total_lines,total_comment_lines,total_blank_lines=total_lines+line[0],total_comment_lines+line[1],total_blank_lines+line[2] print("总代码行数:",total_lines) print("总注释行数:",total_comment_lines,"占%0.2f%%"%(total_comment_lines*100/total_lines)) print("总空行数:", total_blank_lines, "占%0.2f%%"% (total_blank_lines * 100 / total_lines)) if __name__ == '__main__': run(FILE_PATH)
