When splitting an empty string in Python, why does split() return an empty list while split('\n') re
I am using split('\n') to get lines in one string, and found that ''.split() returns an empty list, [] , while ''.split('\n') returns [''] . Is there any specific reason for such a difference?

When should I use double instead of decimal?
...think you've summarised the advantages quite well. You are however missing one point. The decimal type is only more accurate at representing base 10 numbers (e.g. those used in currency/financial calculations). In general, the double type is going to offer at least as great precision (someone corre...
Is nested function a good approach when required by only one function? [closed]
... Nice answer but where is the question? Not here. OP asked whether one can do the above if method_b is only used by method_a. He did not ask anything else. No closure.

... In C, the struct tags, union tags and enumeration tags share one namespace, rather than (struct and union) using two as claimed above; the namespace referenced for typedef names is indeed separate. That means you can't have both 'union x { ... };' and 'struct x { ... };' in a single s...
Named Branches vs Multiple Repositories
...ch changeset and will thus become an immutable part of the history. With clones there will be no permanent record of where a particular changeset came from.

The most common difference (and probably the only one worth worrying about) is lines end with CRLF on Windows, NL on Unix-likes, and CR on older Macs (the situation has changed with OS X to be like Unix). Note the shift in meaning from LF to NL, for the exact same character...
Is there any way to redraw tmux window when switching smaller monitor to bigger one?
...al.app. When you "tmux attach" with bigger resolution monitor from smaller one you previously started tmux, it draws dots around the console. It doesn't fit the new window size.

What are bitwise operators?
