Question

Is there a simple, pythonic, way to generate all n-tuples of a given length from a string?

For example, I would like generateTuples("Hello, World!", 3) to produce the following:

[ "Hel", "ell", "llo", "lo,", "o, ", ", W", " Wo", "Wor", "orl", "rld", "ld!" ]

Answer 1

>>> a = "Hello, World!"
>>> def generate_tuples(string, n):
...     return [string[i:i+n] for i in range(len(string)-n+1)]
... 
>>> generate_tuples(a, 3)
['Hel', 'ell', 'llo', 'lo,', 'o, ', ', W', ' Wo', 'Wor', 'orl', 'rld', 'ld!']
