一行包含以'，'分隔的字符串

Question

in Python, trying to do this thing: I have a line contains several strings separated by ','. I want to erase every string that has particular substring in it. for example:

line: first_name,second_name,every_single_name_exicted,dog,cat.

I want to erase every string that has the word "name" in it + the ',' it has, so the result would be:

line: dog,cat.

and not:

line: ,,,dog,cat

what can I use to achieve that? and how generally can I search particular substring when I don't care what it has on its left or right (like the search option in NotePad for example when you can write name )

Answer 1

s = 'first_name,second_name,every_single_name_exicted,dog,cat'

s = s.split(',')
a = ','.join([i for i in s if 'name' not in i])
print(a)

Try this

Answer 2

• split the string with .split(",")
• Filter by "name" with if not in .
• strip leading / trailing whitespace with .strip()
• join the string with ", ".join()
• Add a dot at the end of the string if necessary with + "."

Like this:

 mystring = "first_name,  second_name, every_single_name_exicted,dog,cat"

 newstring = ", ".join(s.strip() for s in mystring.split(",") if not "name" in s) + "."
