I am new to python and I am having trouble deleting some elements from a list using the del function. I am passing it a simple text file with several lines, creating a list of the lines using splitlines() and then trying to delete the first few elements of the by using del.
When I run it however it just prints out the list without the line deleted. I can however delete everything using del inputfile[:]. It throws no errors and I am a little stuck.
class Zero_Check(object):
def __init__(self):
self.path2file='C:\File2check\Output.txt'
def Parser(self):
print('parser')
inputfile = open(self.path2file).read().splitlines()
del inputfile[4]
print(inputfile)
#for line in inputfile:
# print(line)
if __name__=='__main__':
check=Zero_Check().Parser()

No need to make a class for simple operation
