Remove $ from a column of salaries python 3

问题:

I am trying to print the min and max from a list of salaries that I am reading from a csv file, but first I must remove the $ from the value and don't know how.

I tried iterating through the list and using del[0] and got:

SyntaxError: can't delete literal.

I tried salary.replace("$", " ") and got:

AttributeError: 'list' object has no attribute 'replace'

I appended the salaries column to a list which is an immutable string.

How would I remove the $ from a salary list that looks like [$98,500.85]? Thanks in advance.

Hard to know the exact problem without the code, but you could try one of these:

new_salary = [s.replace("$", "") for s in salary]

or:

new_salary = [s[1:] for s in salary]
