I tried to implent below code and got stucked how to do nested loop to count
instead doing another logic and parsing:
import re
def GetName(input_string):
myName=input_string.split()
myName1= myName[1]
return myName1
def GetAge(input_string):
myAge=input_string.split()
myAge1= myAge[2]
return myAge1
file = open('mylogfile')
log_data = file.readlines()
print 'entered'
for eachline in log_data:
input_string = eachline
if 'name' in input_string:
sometextval = GetName(input_string)
print "name", sometextval
if 'Age' in input_string:
sometextval2 = GetAge(input_string)
print "Age", sometextval2
Now get stuck to get count for total_late time as it is part of name, age so
how to write logic which counts as a part of group.
any help will be grateful.
