从字符串中删除额外的逗号

Question

我无法从以下字符串列表中删除额外的逗号

[',156,151,2016-06-07',',160,147,2016-03-16',',99,91,2016-06-11']

我尝试使用加入和删除，但它没有工作

期待如下结果

['156,151,2016-06-07','160,147,2016-03-16','99,91,2016-06-11']

请帮助我......提前谢谢

Answer 1

您可以使用列表理解：

>>> l = [',156,151,2016-06-07',',160,147,2016-03-16',',99,91,2016-06-11']
>>> l = [i.lstrip(',') for i in l]
>>> l
['156,151,2016-06-07', '160,147,2016-03-16', '99,91,2016-06-11']

Answer 2

只需使用str.replace：

newArr = []
for line in arr:
    newArr.append(line.replace(',', '')

Answer 3
