Count how many text files in a directory using python 2.7 and edit them -


i need counting amount of files in directory/folder (windows 7) in python if there more 20 .txt files can delete there 20 files .txt. if create one, using python, deletes oldest one.

any answers helpful, thank you.

import os (_, _, my_files) = os.walk("c:\\users\\guest.user\\task2").next() amount = len([f f in my_files if f.endswith('.txt')])  print amount  if amount > 20: #this next problem - needs truncate file once there more 20

count txt files

import os   (_, _, my_files) = os.walk('some_directory').next() print len([f f in my_files if f.endswith('.txt')])

count txt files , delete ones that're beyond first 10

import os   (_, _, my_files) = os.walk('some_directory').next() if len([f f in my_files if f.endswith('.txt')]) > 10:     f in my_files[9:]:         os.remove(os.path.join('some_directory', f))

count txt files , delete after x-number of files

import os   my_directory = 'some_directory' max_files = 20  (_, _, my_files) = os.walk(my_directory).next()  if len([f f in my_files if f.endswith('.txt')]) > max_files:     f in my_files[max_files-1:]:         os.remove(os.path.join(my_directory, f))

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
