[英]In Python 3.x, how do I replace certain items in a list then print list as a string
[英]How do I replace certain pieces in a string in a list in python?
['Parent=transcript:Zm00001d034962_T001', 'Parent=transcript:Zm00001d034962_T002', 'Parent=transcript:Zm00001d034962_T003', 'Parent=transcript:Zm00001d034962_T003', 'Parent=transcript:Zm00001d034962_T004', 'Parent=transcript:Zm00001d034962_T005', 'Parent=transcript:Zm00001d034962_T005', 'Parent=transcript:Zm00001d034962_T005']
这就是它的样子。
我想替换Parent=transcript:
和_T00
请帮忙。 不确定使用什么命令
使用 python 的内置replace()
function。 对于最后一部分,如果总是 5 个字符,您可以轻松地排除它们:
items = [
'Parent=transcript:Zm00001d034962_T001',
'Parent=transcript:Zm00001d034962_T002',
'Parent=transcript:Zm00001d034962_T003',
'Parent=transcript:Zm00001d034962_T003',
'Parent=transcript:Zm00001d034962_T004',
'Parent=transcript:Zm00001d034962_T005',
'Parent=transcript:Zm00001d034962_T005',
'Parent=transcript:Zm00001d034962_T005'
]
# use enumerate to replace the item in the list
for index, item in enumerate(items):
# this replaces the items with an empty string, deleting it
new_item = item.replace('Parent=transcript:', '')
# this accesses all the characters in the string minus the last 5
new_item = new_item[0:len(new_item) - 5] + "whatever you want to replace that with"
# replace the item in the list
items[index] = new_item
我假设您想将以下字符串替换为''
将Parent=transcript:
替换为''
将_T00
替换为''
例如, 'Parent=transcript:Zm00001d034962_T001'
将被替换为'Zm00001d0349621'
。
_T001
的结尾字符串1
将连接到Zm00001d034962
。
如果这是您的预期结果,则代码为:
new_list = [x.replace('Parent=transcript:','').replace('_T00','') for x in input_list]
print (new_list)
new_list 的new_list
将是:
['Zm00001d0349621', 'Zm00001d0349622', 'Zm00001d0349623', 'Zm00001d0349623', 'Zm00001d0349624', 'Zm00001d0349625', 'Zm00001d0349625', 'Zm00001d0349625']
请注意,您可以将''
替换为您想要的新字符串。 我已将其标记为''
,因为我不知道您的新替换字符串将是什么。
