报错 re.error: bad escape \L at
原因 python 自带的 re 有问题
修改成 regex 即可
安装 regex
pip install regex
使用
import regex as re
关键替换代码 使用 re.sub
str_des_file_0 = re.sub('(?s)<name>.*</name>', r"<name>w</name>", str_file) images_dir_path = "D:/voc2007/JPEGImages/" image_path = os.path.join(images_dir_path, i) path_str = r"<path>{}</path>".format(image_path) # print(path_str) str_des_file_1 = re.sub('(?s)<path>.*</path>', path_str, str(str_des_file_0))
替换完整代码
import os, shutil import regex as re def mv_floder(path): dir_abs_path = os.path.abspath(path) res_dir = os.path.dirname(dir_abs_path) res_dir = os.path.join(res_dir, "voc2007") if os.path.exists(res_dir): shutil.rmtree(res_dir) os.mkdir(res_dir) annotations_dir = os.path.join(res_dir, "Annotations") if not os.path.exists(annotations_dir): os.mkdir(annotations_dir) JPEGImages_dir = os.path.join(res_dir, "JPEGImages") if not os.path.exists(JPEGImages_dir): os.mkdir(JPEGImages_dir) print(dir_abs_path) for root, y, files in os.walk(dir_abs_path): for i in files: file_path = os.path.join(root, i) if root.find("annotations") != -1 or root.find("Annotations") != -1: des_file_path = os.path.join(res_dir, "Annotations") des_file_path = os.path.join(des_file_path, i) with open(file_path, "r", encoding="utf8") as f: str_file = f.read() # print(str_file) str_des_file_0 = re.sub('(?s)<name>.*</name>', r"<name>w</name>", str_file) images_dir_path = "D:/voc2007/JPEGImages/" image_path = os.path.join(images_dir_path, i) path_str = r"<path>{}</path>".format(image_path) # print(path_str) str_des_file_1 = re.sub('(?s)<path>.*</path>', path_str, str(str_des_file_0)) with open(des_file_path, "w", encoding="utf8") as f_des: # print(str_des_file) f_des.write(str_des_file_1) # shutil.copyfile(file_path, des_file_path) if root.find("JPEGImages") != -1: des_file_path = os.path.join(res_dir, "JPEGImages") des_file_path = os.path.join(des_file_path, i) shutil.copyfile(file_path, des_file_path) if __name__ == "__main__": mv_floder("./20200903-1jieguo") mv_floder("./20200903-2")
