How to remove a specific character from some specific strings within a Python list?

Question

I have a list of examples:

['#[Header]', '#Application Name\tLCsolution', '#Version\t1.24']

I would like to know how to remove a specific character, such as the # of all elements of the list, or, if I prefer, of only a few elements, such as [0:1].

You can use the replace to replace unwanted characters in your string with an empty string:

'#[Header]'.replace('#', '')  # '[Header]'

To do this in all strings in the list, just use a list comprehension to apply the replace in all elements:

minha_lista = ['#[Header]', '#Application Name\tLCsolution', '#Version\t1.24']
minha_lista = [s.replace('#', '') for s in minha_lista]

Or do the same for just one Cup:

minha_lista = ['#[Header]', '#Application Name\tLCsolution', '#Version\t1.24']
minha_lista[:2] = [s.replace('#', '') for s in minha_lista[:2]]
