Even prouder of the 1 liner!
In fact I'm going to post it, because I think any student who can walk
his instructor through how my one-liner works deserves the marks. Of
course, any student who presents this as a solution and is unable to walk
their instructor through it should be failed for stupidity and plagiarism!
t = ["pythonpythonpyth", "DOLORIUMD", "HELLOLHELLO", "thewordword",
"barbaz", "dibdibdobdibdibdob"]
def baseword(s):
"""find shortest sequence which repeats to generate s"""
return s[0:["".join([s[0:x]for k in range(int(len(s)/x)+1)])[0:len
(s)]for x in range(1,len(s)+1)].index(s)+1]
for w in t:
print(baseword(w))
p.s. I really want to be in the room when the instructor asks this
student to come up in front of the class and explain how his solution
works!
