range
Python IndexError: list index out of range
Replace: for i in range(1, 31): with: for d in Data[1:31]: #since you have range(1,31). Do Data[1:] if you just want to skip the first OneDate.append(d[0]) OneClose.append(d[4]) This usually happends when Data array has less than 31 indices. Also ensure d array has atleast 5 items, else d[4] will also throw a similar error. Use: … Read more
Python 3 range Vs Python 2 range
Python 3 uses iterators for a lot of things where python 2 used lists.The docs give a detailed explanation including the change to range. The advantage is that Python 3 doesn’t need to allocate the memory if you’re using a large range iterator or mapping. For example for i in range(1000000000): print(i) requires a lot … Read more
Is there a need for range(len(a))?
If you need to work with indices of a sequence, then yes – you use it… eg for the equivalent of numpy.argsort…: >>> a = [6, 3, 1, 2, 5, 4] >>> sorted(range(len(a)), key=a.__getitem__) [2, 3, 1, 5, 4, 0]
PHP: Create an array for a range

range over character in python
This is a great use for a custom generator: Python 2: def char_range(c1, c2): “””Generates the characters from `c1` to `c2`, inclusive.””” for c in xrange(ord(c1), ord(c2)+1): yield chr(c) then: for c in char_range(‘a’, ‘z’): print c Python 3: def char_range(c1, c2): “””Generates the characters from `c1` to `c2`, inclusive.””” for c in range(ord(c1), ord(c2)+1): … Read more
Range as dictionary key in Python
It is possible on Python 3 — and on Python 2 if you use xrange instead of range: stealth_check = { xrange(1, 6) : ‘You are about as stealthy as thunderstorm.’, #… } However, the way you’re trying to use it it won’t work. You could iterate over the keys, like this: for key in … Read more
Is there a range class in C++11 for use with range based for loops?
The C++ standard library does not have one, but Boost.Range has boost::counting_range, which certainly qualifies. You could also use boost::irange, which is a bit more focused in scope. C++20’s range library will allow you to do this via view::iota(start, end).
