简短而简单

import os
directory_path = '/home/xyz/'
No_of_files = len(os.listdir(directory_path))

def count_em(valid_path):
   x = 0
   for root, dirs, files in os.walk(valid_path):
       for f in files:
            x = x+1
print "There are", x, "files in this directory."
return x

摘自本文

对于所有类型的文件，包括子目录(Python 2):

import os

lst = os.listdir(directory) # your directory path
number_files = len(lst)
print number_files

只有文件(避免子目录):

import os

onlyfiles = next(os.walk(directory))[2] #directory is your directory path as string
print len(onlyfiles)

我解决了这个问题，同时通过谷歌Colab计算谷歌驱动器目录中的文件数量，通过将自己定向到目录文件夹by

import os                                                                                                
%cd /content/drive/My Drive/  
print(len([x for x in os.listdir('folder_name/']))  

普通用户可以尝试

 import os                                                                                                     
 cd Desktop/Maheep/                                                     
 print(len([x for x in os.listdir('folder_name/']))  

import os

total_con=os.listdir('<directory path>')

files=[]

for f_n in total_con:
   if os.path.isfile(f_n):
     files.append(f_n)


print len(files)

import os

_, _, files = next(os.walk("/usr/lib"))
file_count = len(files)
