  • Difference between . items () and . keys () - Stack Overflow
    (As jathanism notes in the comments, in older versions of Python (2 x), using iteritems() is a better option than items() as it does not produce a list - 3 x users like myself don't need to worry as items() produces a dictionary view, which is lazy )

  • How do I get the length of a list? - Stack Overflow

  • Pulling full work item information from a single DevOps API query

  • html - Flexbox: 4 items per row - Stack Overflow
    This is the reason items don't wrap to form a grid in some cases In this case, the main problem is flex-grow: 1 on the flex items The flex-grow property doesn't actually size flex items Its task is to distribute free space in the container So no matter how small the screen size, each item will receive a proportional part of the free space
