Here is a simple program to print the file size in bytes and megabytes. # get file size in python import os file_name = "/Users/pankaj/abcdef.txt" file_stats = os.stat(file_name) print(file_stats) print(f'File Size in Bytes is {file_stats.st_size}') print(f'File Size in Meg...
Python File(文件) 方法概述readline() 方法用于从文件读取整行,包括 "\n" 字符。如果指定了一个非负数的参数,则返回指定大小的字节数,包括 "\n" 字符。语法readline() 方法语法如下:fileObject.readline(size)参数size -- 从文件中读取的字节数。
fileinfo = os.stat(fileName) file_size = int(fileinfo.st_size)/1024 return file_size except Exception as reason: print_ztp_log(f"Get file size failed. reason = {reason}", LOG_ERROR_TYPE) return file_size def get_file_size(file_path=''): """Return the size of a file in the ...
