I am appending a tuple to the list if I don't find the string.
if list2[0] in hr:
print "X"
else:
hr.append((list2[0], 1))
print "X"
is arbitary. But the code section is not going into the if
block.
Also I want to increment the value of the second item of the tuple of the list hr
Please provide suggestions.
Edit:
list2
is a list of the form ['09', '14', '16']
And hr
is the list of tuples as can be seen from the code hr.append((list2[0], 1))
hr
is of the form [('09', 1), ('18', 1)]
Also the increment is to change [('09', 1), ('18', 1)]
to [('09', 1), ('18', 2)]
when encounter '18'
again in list2
All the operations are being carried out inside a loop reading a file.
Try this:
item_found = False
for index, item in enumerate(hr):
if list2[0] == item[0]:
item_found = True #found the item
hr[index] = (item[0], item[1]+1) #increment by 1
break #don't loop more than we need to
if not item_found:
hr.append((list2[0], 1)) #add new item
