## Functionalities (with parameters description):

#### textsnipper.tkeypos(keyword, text)
	- Return all starting and ending position of the keyword from a giuven text
	- Output will be in list of tuples

#### textsnipper.extract_sents(keyword, text, format='l') 
	- This function extract all the sentences from a giuven text that contain the keyword
	- By default format is l, that means list of sentences. If we pass p then the outpt format will be paragraph.
    
#### textsnipper.extract_words(keyword, text, left_w=0, right_w=1)
	- This function extract the neighbourhood words of the keyword from a given text.
	- In case of left_w = 0, right_w = n it will provide n number of words from the right side of the keyword, n should be an integer
	- In case of left_w = m, right_w = 0 it will provide m number of words from the left side of the keyword, m should be an integer
	- In case of left_w = m, right_w = n it will provide m number of words from the left side of the keyword, n number of words from the right side of the keyword
    
#### textsnipper.extract_chars(keyword, text, left_chr=0, right_chr=1)
    - This function extract the neighbourhood charecters of the keyword from a given text.
	- In case of left_chr = 0, right_chr = n it will provide n number of charecters from the right side of the keyword, n should be an integer
	- In case of left_chr = m, right_chr = 0 it will provide m number of charecters from the left side of the keyword, m should be an integer
	- In case of left_chr = m, right_chr = n it will provide m number of charecters from the left side of the keyword, n number of charecters from the right side of the keyword

#### textsnipper.left_texts(keyword, text, occurrence='all')
	- This function will return the left side of the keyword i.e. from the keyword to beginning of the text based on all occurence of keyword
	- If we pass the 1 or 2 in occurence then it will return the left side text of 1st or 2nd occurence of the keyword from a text, Occurene should be 1,2,...,n,'all'
	- Provid ethe output in list format if occurence is all
	
#### textsnipper.right_texts(keyword, text, occurrence='all')
	- occurence means the repeation of the keyword in  text
	- This function will return the right side of the keyword i.e. from the keyword to ending of the text based on all occurence of keyword
	- If we pass the 1 in occurence then it will return the right side text of 1st occurence of the keyword from a text, Occurene should be 1,2,...,n,'all'
	- Provid ethe output in list format if occurence is all
	
#### textsnipper.between_fixed_keyword(keyword, text)
	- Provide the part of the text between two same keyword
	- Output will come in list format

#### textsnipper.between_distinct_keywords(keyword_start, keyword_end, text, keyword_start_occurence=1, keyword_end_occurence=1)
	- keyword_start_occurence indicates the the repeatition of the starting keyword in given string
	- keyword_end_occurence indicates the the repeatition of the starting  keyword in given string
	- Provide the part of the text between two distinct keyword
	- Output will come in list format
	- For getting all snap texts in list format pass keyword_start_occurence = 0 and keyword_end_occurence = 0

#### textsnipper.text_keyword_remover(remover_list, text, replaced_by)
	- This function remove the keyword from the text
	- Non alphanumeric charecters need to be write in regex format

### textsnipper.dkeypos(keyword, dataframe)
	- Return all cells position of the keyword from a giuven dataframe
	- Output will be in list of tuples

### textsnipper.dataframe_keyword_remover(remover_list, dataframe, replaced_by)
	- This function remove the keyword from the dataframe
	- Non alphanumeric charecters need to be write in regex format
