1. 目录下文件解析：特定文件、文件列表、文件数
- Windows文件目录分格使用“ / ” 或 “ \\ ”
- 文件目录路径包含空格的，绝对路径使用“双引号”，保证文件路径的可识别性
- 保存和读取结果时，使用 encoding='UTF-8'
- 可以添加对文件目录的过滤
# FileFindInFolder.pyimport osfd = "H:/My/Study/Python" # source folder
ef = '.pdf' # specified file suffix for finding
rf = "c:/record.txt" # final result output
lrf = [] # list for result output
cn = 0 # count for file findfor root, dirs, files in os.walk(fd): # travel and check all folders and filesfor i in files:if i.endswith(ef): # file specified endingcn = cn + 1fpath = root + i # file full pathlrf.append(fpath)# result output and save
with open(rf, 'w', encoding='UTF-8') as fp:fp.write("Total: " + str(cn) + '\n')for i in lrf:fp.write(i + '\n')# read file and show content
with open(rf, 'r', encoding='UTF-8') as fp:fl = fp.readlines()for i in fl:print(i)>>>

- 文件读取来自linux系统
- 查找当前文件夹所有文件并显示文件大小，结果输出到指定文件
- 文本样例
