我是python的新手,我无法使用del
函数从列表中删除某些元素。我传递了一个包含多行的简单文本文件,使用splitlines()
创建行列表,然后尝试使用del
删除前几个元素。
当我运行它时,它只打印出列表而不删除行。但是,我可以使用del inputfile[:]
删除所有内容。它没有抛出任何错误,我有点卡住了。
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()
驱动器C中的卷是OSDisk 卷序列号为F0A9-9FB7
