很多時(shí)候，查看一個(gè)文件夾下的每個(gè)文件大小可以輕易的做到，因?yàn)槲募竺婢褪俏募叽纾侨绻枰榭匆粋€(gè)文件夾下面所有的文件夾對(duì)應(yīng)的尺寸，就發(fā)現(xiàn)需要把鼠標(biāo)放到對(duì)應(yīng)的文件夾上，稍等片刻才會(huì)出結(jié)果。

有時(shí)候，我們需要查看幾十個(gè)甚至于上百個(gè)文件夾，找出包含文件最多，空間占用最大的那個(gè)，就比較麻煩了。這段代碼是我以前的代碼，可以按大小排序輸出文件夾大小到txt文件，供使用的方便。

格式化當(dāng)時(shí)花了很長(zhǎng)時(shí)間，最后發(fā)現(xiàn)使用‘YaHei.Consolas’字體可以解決，對(duì)齊后輸出結(jié)果看起來(lái)還算舒服。

上代碼：

import osimport datetime def get_folder_size(path): folder_size = 0 if not os.path.exists(path): return folder_size if os.path.isfile(path): folder_size = os.path.getsize(path) return folder_size try: if os.path.isdir(path): with os.scandir(path) as directory_lists:for directory_list in directory_lists: if directory_list.is_dir(): sub_folder_size = get_folder_size(directory_list.path) # 遞歸獲取大小 folder_size += sub_folder_size elif directory_list.is_file(): file_size = os.path.getsize(directory_list.path) folder_size += file_size return folder_size except: pass # 以下主要是為了格式化輸出def get_file_length(file_name): characters = list(file_name) ascii_length = 0 utf8_length = 0 for character in characters: if ord(character) < 128: ascii_length += 1 else: utf8_length += 2 return ascii_length + utf8_length def main(basedir): with os.scandir(basedir) as dirs: directory_size = [] for dir in dirs: try:if not dir.is_file(): dirsize = round(get_folder_size(dir.path) / 1000000) # return the file size in Mb resformat = [dir.name, dirsize] directory_size.append(resformat) except:pass results = sorted(directory_size, key=lambda x: x[1], reverse=True) # return a list ordered by size results = [[i[0], ’文件夾大小：’ + str(i[1]) + ’ Mb’] for i in results] with open(basedir + os.sep + datetime.date.today().isoformat() + ’.txt’, ’a+’) as f: for result in results:# 按照50的寬度格式化輸出結(jié)果len1 = 50 - get_file_length(result[0]) + len(result[0])len2 = 25 - get_file_length(result[1]) + len(result[1])f.writelines(’{:<{len1}s} {:>{len2}s}n’.format(result[0], result[1], len1=len1, len2=len2)) print(’The result was successfully saved in the directory with date as file name.’) if __name__ == '__main__': basedir = input('Please input the directory you would like to know the sizes: ') main(basedir)

如果輸入相應(yīng)的文件夾路徑，輸出結(jié)果如下：

有時(shí)間我再簡(jiǎn)化一下代碼，目前先這樣。

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持好吧啦網(wǎng)。
