[英]Remove first occurrence that matches criteria from a list
Suppose I have a list of strings: 假设我有一个字符串列表:
first item
second item
# first commented item
third item
# second commented item
How do I remove the first item that starts with #
from the list? 如何从列表中删除以#
开头的第一个项目?
Expected result: 预期结果:
first item
second item
third item
# second commented item
>>> items = ["First", "Second", "# First", "Third", "# Second"]
>>> for e in items:
... if e.startswith('#'):
... items.remove(e)
... break
...
>>> items
['First', 'Second', 'Third', '# Second']
items = ["First", "Second", "# First", "Third", "# Second"]
for i in xrange(len(items)):
if items[i][0] == '#':
items.pop(i)
break
print items
