python获取文件夹下数量
import os totalSize = 0 fileNum = 0 dirNum = 0 def visitDir(path): global totalSize global fileNum global dirNum for lists in os.listdir(path): sub_path = os.path.join(path, lists) print(sub_path) if os.path.isfile(sub_path): fileNum = fileNum+1 # 统计文件数量 totalSize = totalSize+os.path.getsize(sub_path) # 文件总大小 elif os.path.isdir(sub_path): dirNum = dirNum+1 # 统计文件夹数量 visitDir(sub_path) # 递归遍历子文件夹 def sizeConvert(size): # 单位换算 K, M, G = 1024, 1024**2, 1024**3 if size >= G: return str(size/G)+'G Bytes' elif size >= M: return str(size/M)+'M Bytes' elif size >= K: return str(size/K)+'K Bytes' else: return str(size)+'Bytes' def main(path): if not os.path.isdir(path): print('Error:"', path, '" is not a directory or does not exist.') return visitDir(path) def output(path): print('The total size of '+path+' is:'+sizeConvert(totalSize)) print('The total number of files in '+path+' is:',fileNum) print('The total number of directories in '+path+' is:',dirNum) if __name__ == '__main__': path = r'E://Files' main(path) output(path)
