# Here, For This Tutorial
#
# I am using
#
# Operating System : Ubuntu 16.04
# Python Version : python 2.7.12
# Editor : ipython notebook

# Import Module

#
# fnmatch Module allow user to compare file and folders
# names with given specific pattern.
# fnmatch module supports Unix shell-style Patterns For
# Comparing File And Folders Names.
#
# In Short, This Module Allow You to Search File and Folders
# Name is Specific patterns.
#
# So, Let Me show you A Example.
# But First, We needs Some Files To Test Glob Module
#
#
for i in ['file1.txt','file2.doc','file3.py','file4.extension','123456.c','Test123.txt']:
f = open(i,'w')
f.close()
# Now, we Are Ready To Test Glob Module.
# So, let's Start
# In This Example, I will try To find any text file that's
# Contains .txt Extension.

# Refrence Of Pattern #
#######################
#---------------------------------------
# Pattern| Meaning |
#---------------------------------------
# * | Match Every Character |
#---------------------------------------
# ? | Match Any Single Character |
#---------------------------------------
# [seq] | Any Character From Sequence |
#---------------------------------------
# [!seq] |Any Character Not In Sequence |
#---------------------------------------

#
# Here,First I Am Showing Simple usages Of Os.listdir function.
# os.listdir() function provide us to list of file and folders present
# In any specific path given as argument.
#
print "printing All Files And Folders, Present In Current Directory : "
#
#
for i in os.listdir("."):
print " ==> ",i
Output : [5]
printing All Files And Folders, Present In Current Directory :
==> file3.py
==> .ipynb_checkpoints
==> file4.extension
==> 123456.c
==> fnmatch_part_1.ipynb
==> Test123.txt
==> file1.txt
==> file2.doc
Input : [6]
#
#
# Now, let's Try to find file that contain '.txt' extension
#
for i in os.listdir("."):
if fnmatch.fnmatch(i, '*.txt'):
print " Txt File ==> ",i
Output : [6]
Txt File ==> Test123.txt
Txt File ==> file1.txt
Input : [7]
#
# As You can See In Our previous Example, we Successfully find
# txt file, present in our current directory.
#
# Now,Let's try More Situations:
#
for i in os.listdir("."):
if fnmatch.fnmatch(i, '*.txt'):
print "\n Txt File ==> ",i
elif fnmatch.fnmatch(i, '*.c'):
print "\n C Codes ==> ",i
elif fnmatch.fnmatch(i, '*.py'):
print "\n Python Script ==> ",i
elif fnmatch.fnmatch(i, '*.doc'):
print "\n Doc File ==> ",i
else:
print "\n Unknown File ==> ",i
Output : [7]
Python Script ==> file3.py
Unknown File ==> .ipynb_checkpoints
Unknown File ==> file4.extension
C Codes ==> 123456.c
Unknown File ==> fnmatch_part_1.ipynb
Txt File ==> Test123.txt
Txt File ==> file1.txt
Doc File ==> file2.doc
