Delete character in sublist-CodePudding

I have a list of sublists in the following format:

[['1023869', '-0.137869328454', '0.318039373746', '1.243\n'], ['1023870', '-0.121434633793', '0.324670024328', '1.243\n']]

I want to delete "\n" from the last element in the sublist.

CodePudding user response：

Use a list comprehension with rstrip:

[sublist[:-1]   [sublist[-1].rstrip()] for sublist in lst]

[['1023869', '-0.137869328454', '0.318039373746', '1.243'], 
 ['1023870', '-0.121434633793', '0.324670024328', '1.243']]

CodePudding user response：

Just mutable last element in given list.

for subList in alist:
  subList[-1] = subList[-1][:-1]

>>> alist
>>> [['1023869', '-0.137869328454', '0.318039373746', '1.243'], ['1023870', '-0.121434633793', '0.324670024328', '1.243']]
