Python’s str.split divides a string into a list of substrings. Pass a separator such as ':' to split fields, or omit the argument to treat any run of spaces, tabs, and newlines as one delimiter. section 2.8 section 5.7
Use string splitting as part of larger transformations:
- Split a sentence into words, transform each word, collect the results in a list, and recombine them with str.join. section 2.7 section 2.8
- Split file lines into fields, but discard comments and blank lines before indexing the resulting list. section 5.7
- Split whitespace-separated numbers, convert valid elements with int, filter with str.isdigit, and sum the results. section 7.7
- Use regular expressions with re.split when more than one separator, such as commas and ::, is required. section 2.8
Translate a sentence word by word
sentence = 'this is a test translation' words = sentence.split() translated = [word[1:] + word[0] + 'ay' for word in words] print(' '.join(translated)) This produces: histay isway away estay ranslationtay. Splitting supplies individual words, while join prints the accumulated results on one line. section 2.7 section 2.8
s = 'abc def ghi' #1
s.split(' ') #2
s.split() #3
Compare an explicit space separator with default whitespace handling: split(' ') preserves empty fields between repeated spaces, while split() treats runs of whitespace as one delimiter. section 2.8
