For a one-liner:
x[slice(*map(int, x[1:-1].split(':')))]
Thanks.
Almost works :)
For s="[2]" and s="[1:2]" it's fine. But, if I have
s = "[:2]" then I get:
x[slice(*[int(i) for i in s.strip("[]").split(":")])]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: ''
Similar problem with [2:].
Ideas?
try:
start, end = s[1:-1].split(':')
except ValueError:
start = int(s[1:-1] # only one value specified
end = start+1
start = int(start) if start else 0
end = int(end) if end else len(x)
x[start:end]
