How can I extract text from a string when begining and ending strings are given?
s = "Waiting is a 2015 Indian comedy-drama film directed by Anu Menon, released in India on 27 May 2016. Produced by Priti Gupta of Ishka Films and Manish Mundra of Drishyam Films, the film was co-written by Menon and James Ruzicka"
begining = "Produced"
ending = "Films"
Output should be:
Produced by Priti Gupta of Ishka Films and Manish Mundra of Drishyam Films
The solution using str.find and str.rfind functions with an additional check (assuring that both words are found):
s = "Waiting is a 2015 Indian comedy-drama film directed by Anu Menon, released in India on 27 May 2016. Produced by Priti Gupta of Ishka Films and Manish Mundra of Drishyam Films, the film was co-written by Menon and James Ruzicka"
begining_str = "Produced"
ending_str = "Films"
b_pos = s.find(begining_str)
e_pos = s.rfind(ending_str)
result = s[b_pos:e_pos + len(ending_str)] if b_pos != -1 and e_pos != -1 else ''
print(result)
The output:
Produced by Priti Gupta of Ishka Films and Manish Mundra of Drishyam Films
You can make use of the index method of strings in python and use slicing.
For your particular example something like this should work:
s[s.index(b):s.index(e)+len(e)]
What the code above does is the following: s.index(b) finds the first occurrence from the left of the string in b. Similar s.index(e). As you want to include the end word as well, we simply add the number of chars in the end string to the last index. s[x:y] gives you a "slice" of a string from x to y.
str, as this shadows the built instr()method. I know what you posted is just an example, I thought I'd point this out just in case you didn't know :-)
