如何使用python批量修改文本文件编码格式

import sys import chardet import codecs def get_encoding_type(fileName): '''print the encoding format of a txt file ''' with open(fileName, 'rb') as f: data = f.read() encoding_type = chardet.detect(data) #print(encoding_type) return encoding_type # such as {'encoding': 'GB2312', 'confidence': 0.99, 'language': 'Chinese'} def convert_encoding_type(filename_in, filename_out, encode_in="gb2312", encode_out="utf-8"): '''convert encoding format of txt file ''' #filename_in = 'flash.c' #filename_out = 'flash_gb2312.c' #encode_in = 'utf-8'  # 输入文件的编码类型 #encode_out = 'gb2312'# 输出文件的编码类型 with codecs.open(filename=filename_in, mode='r', encoding=encode_in) as fi: data = fi.read() with open(filename_out, mode='w', encoding=encode_out) as fo: fo.write(data) fo.close() # with open(filename_out, 'rb') as f: #     data = f.read() #     print(chardet.detect(data)) if __name__=="__main__": # fileName = argv[1] # get_encoding_type(fileName) # convert_encoding_type(fileName, fileName) filename_of_files = sys.argv[1]   #the file contain full file path at each line with open(filename_of_files, 'rb') as f: lines = f.readlines() for line in lines: fileName = line[:-1] encoding_type = get_encoding_type(fileName) if encoding_type['encoding']=='GB2312': print(encoding_type) convert_encoding_type(fileName, fileName) print(fileName) 

xml_path = './' with open(xml_path , 'rb+') as f:     content = f.read()     codeType = detect(content)['encoding']     content = content.decode(codeType, "ignore").encode("utf8")     fp.seek(0)     fp.write(content)
