Splitting by a pattern
You are given the movies
list where each element stores a movie name, its release date, and the director (e.g. "The Godfather, 1972, Francis Ford Coppola"
).
Let's practice some splitting with the help of regular expressions. Your task is to retrieve from each element of the list its name and the director. For example, if the element is "The Godfather, 1972, Francis Ford Coppola"
, the result would be:
['The Godfather', 'Francis Ford Coppola']
Eventually, this result should be modified to represent a single string, e.g.
"The Godfather, Francis Ford Coppola"

Exercise instructions
- Compile a regular expression that splits strings in
movies
into a movie name and its director. - Retrieve a movie name and its director using
re.split()
. - Create a new string with a movie name and its director separated by
,
. - Append the resulting string to
movies_without_year
.
