How to get meaningful words by splitting a continuous string?

this one helps. For removing the \n chars strip will only work if they are at beginning and end of string.
You can use split instead and attach string back without the \n if you end up splitting on \n
code :
string.split(' ')

I hope this helps . one possibility is increasing the index size by adding all substrings of the exact same string. so for "abc" you will store: "a","b","c","ab","bc","abc" (it's O(n^2) strings).
one more possibility is using wildcards. index whatever you have, and search for:

wish helps you You can use this function, just pass in your string and the length and it will return the array, like:
code :
var outputString = splitter(shortData['new'], 148);
function splitter(str, l){
    var strs = [];
    while(str.length > l){
        var pos = str.substring(0, l).lastIndexOf(' ');
        pos = pos <= 0 ? l : pos;
        strs.push(str.substring(0, pos));
        var i = str.indexOf(' ', pos)+1;
        if(i < pos || i > pos+l)
            i = pos;
        str = str.substring(i);
    }
    strs.push(str);
    return strs;
}
splitter("This is a string with several characters.\
120 to be precise I want to split it into substrings of length twenty or less.", 20);
["This is a string","with several","characters. 120 to",
"be precise I want","to split it into","substrings of",
"length twenty or","less."]
Is there a nice way splitting a (potentially) long string without splitting in words in Python?

Hope this helps There's a module for that: textwrap
For instance, you can use
code :
print '\n'.join(textwrap.wrap(s, 80))
print textwrap.fill(s, 80)

may help you . As MS Excel limits the number of characters in a cell to 32767, I have to split longer strings in a pandas dataframe into several cells. , Here is the general idea.
code :
# find longest long string, then divide the text 
# into the number of new cols you want, adding a | at
# the division and then later splitting by that |

longest = ""
for x in df_test['Text']:
    if len(x) > len(longest):
        longest = x
    continue

import math 

num_cols = math.floor(len(longest.split(' ')) / 3) # shoot for 3 words per row
for index,row in df_test.iterrows():

    word_str = row['Text']
    word_char_len = len(word_str)
    word_as_list = word_str.split(' ')
    num_words = len(word_as_list)

    col_index = math.ceil(len(word_as_list) / num_cols)

    for _ in range(num_cols - 1):
        word_as_list.insert(col_index,'|')
        col_index += col_index
    new = ' '.join(word_as_list)
    df_test.at[index,'Text'] = new

cols = ['Text'+str(i) for i in range(1,num_cols+1)]
df_test[cols] = df_test.Text.str.split('|',expand=True)
del df_test['Text']                                                                                                                   
print(df_test)
   Date Source    ID            Text1          Text2                Text3
0  2019    FAZ  ID_1  This should be      the first      very long string
1  2018     SZ  ID_2     This is the    second very           long string
2  2019     HB  ID_3     This is the     third very           long string
3  2018     HB  ID_4     This is the    last string    which is very long

will be helpful for those in need To answer your question, Knuth-Morris-Pratt algorithm is powerful and not terribly difficult to implement.
Use strings from /usr/share/dict/words or /usr/dict/words as the patterns.
