Is there an interpreter for C? [closed]
...ng like an interpreter for C. That is, in a Linux terminal I can type in "python" and then code in that interpreter. (I'm not sure interpreter the right word). This is really helpful for testing different things out and I'm curious if something similar exists for C. Though I doubt it. The only ...
Automatically remove Subversion unversioned files
...on to do this:
svn cleanup --remove-unversioned
Before that, I use this python script to do that:

Since 2003, Python's list sort has used an algorithm known as timsort

running on partially sorte...

A better performing alternative is to use df['dates'].dt.floor('d'). Strictly speaking, it does not "keep only date...
Bitwise operation and usage
...10 0101
1111 1111 << 4 gives 1111 0000
Note that the left shift in Python is unusual in that it's not using a fixed width where bits are discarded - while many languages use a fixed width based on the data type, Python simply expands the width to cater for extra bits. In order to get the dis...
