Python 删除嵌套列表中的前符号符号

我正在尝试从嵌套列表中删除%符号。所有子列表都可以包含字符串元素或整数元素。我的问题是，如何从包含%sign的元素中删除%sign

例如：

input:
[[Name, cnt , RSH, Total],
[XXXX, 000000093, 0.2% ,000000000 ,0.0%],
[YYYY, 000000064, 0.1% ,000000000 ,0.0%]]

output:
[[Name, cnt , RSH, Total],
[XXXX, 000000093, 0.2 ,000000000 ,0.0],
[YYYY, 000000064, 0.1 ,000000000 ,0.0]]

提前感谢

蟒蛇疗法是：

b = [[j.split('%')[0] for j in i] for i in a]

输出为：

 [['Name', 'cnt', 'RSH', 'Total'],
  ['XXXX', '000000093', '0.2', '000000000', '0.0'],
  ['YYYY', '000000064', '0.1', '000000000', '0.0']]
