I am facing problem parsing multiple yaml files in directory. The for loop runs only for 1st file in directory.

Check my code

#!/usr/bin/env python

import os
import yaml
import copy

class iplMatch:
    # This is Match class.
    iMatchCount = 0
    iMatchID = 0
    strSourceFileName = 0
    def __init__(self, strFileName):
        print strFileName
        self.strSourceFileName = strFileName
        stream =  file(strFileName, 'r')
        yamlMatchData = yaml.safe_load(stream)
        self.strMatchVenue = yamlMatchData['info']['venue']
        self.strMatchCity = yamlMatchData['info']['city']
        self.strMatchDate = str(yamlMatchData['info']['dates'][0])
        self.strHomeTeam = yamlMatchData['info']['teams'][0]
        self.strAwayTeam = yamlMatchData['info']['teams'][1]
        self.strWinner = yamlMatchData['info']['outcome']['winner']
        self.strTossWinner = yamlMatchData['info']['toss']['winner']
        self.strTossDecision = yamlMatchData['info']['toss']['decision']
        self.strWinType = yamlMatchData['info']['outcome']['by']
        self.strMoM = yamlMatchData['info']['player_of_match'][0]


    def displayMatchDetails(self):
        # print "Match : ", self.strHomeTeam, " _vs_ ", self.strAwayTeam
        print "" \
              "Venue : ", self.strMatchVenue, ",", self.strMatchCity
        print "" \
              "On : ", self.strMatchDate
        print "" \
              "Toss Won by : ", self.strTossWinner, " Decided to ", self.strTossDecision
        print "" \
              "Won by ", self.strWinner, " by ", self.strWinType.keys()[0], " : ", self.strWinType.values()[0]
        print "" \
              "Man of the Match : ", self.strMoM
        print self.strSourceFileName

    def reset(self):
        self.strMatchVenue = 0
        self.strMatchCity = 0
        self.strMatchDate = 0
        self.strHomeTeam = 0
        self.strAwayTeam = 0
        self.strWinner = 0
        self.strTossWinner = 0
        self.strTossDecision = 0
        self.strWinType = 0
        self.strMoM = 0


#Start Main

# arrayIplMatches = []
root = 'C:/Users/pkya/Documents/DWH/ipl/'
FileList = os.listdir(root)
print FileList

for fn in FileList:
    print "inside for :", fn
    strAbsFilePath = root + fn
    print strAbsFilePath
    if os.path.isfile(strAbsFilePath):
        print "inside if"
        # os.path.join(root, f)
        iplMatchData = iplMatch(strAbsFilePath)
        # arrayIplMatches.append(copy.copy(iplMatchData))
        iplMatchData.displayMatchDetails()
        print "Done Display"
        print iplMatchData
        iplMatchData.reset()
        print "Done Reset"
        print iplMatchData
    break

now the directory specified contains 3000 yaml files

@D-Pkya you have a break in the for loop causing the loop to end after the first iteration.
