Two types of usage are supported:
(1) Merging all files under a folder (ignoring non-file items such as folders)
(2) Display of merged multiple files.
Copy CodeThe code is as follows:
Import Sys
Import OS
'''
Usage (1): Merge_files pathname
Pathname is directory and the merge files in pathname directory
Usage (2): Merge_files file1 file2 [file3[...]
'''

For file in Fileslist:
With open (file, "RB") as C_FP:
Fsize = Os.stat (file). st_size
Count = Fsize&file_slim
While count>0:
