++i will increment the value of i, and then return the incremented value. i = 1; j = ++i; (i is 2, j is 2) i++ will increment the value of i, but return the original value that i held before being incremented. i = 1; j = i++; (i is 2, j is 1) For a for loop, either works. ++i seems more common, … Read more
New to programming and python altogether. In the book I’m learning from, the author suggested I find out the purpose of Pydoc. I did a google search on it, and found a match (from Gnome Terminal) but it didn’t make much sense to me. Anyone mind simplifying a bit?
You can convert char to int and viceversa easily because for the machine an int and a char are the same, 8 bits, the only difference comes when they have to be shown in screen, if the number is 65 and is saved as a char, then it will show ‘A’, if it’s saved as … Read more

clsx is generally used to conditionally apply a given className This syntax means that some class will only be applied if a given condition evaluates to true In this example [classes.menuOpen] (which will evaluate to something like randomclassName123) will only be applied if open === true clsx basically outputs a string interpolation. So you don’t have to necessarily use it, although is a common practice. … Read more

I have the following source code When I try to compile it I get the following error: What am I doing wrong? Any help appreciated.
For a dataframe df, one can use any of the following: len(df.index) df.shape[0] df[df.columns[0]].count() (== number of non-NaN values in first column) Code to reproduce the plot:
Read Byte by Byte and check that each byte against ‘\n’ if it is not, then store it into bufferif it is ‘\n’ add ‘\0’ to buffer and then use atoi() You can read a single byte like this See read()
I need to know the most efficient way of installing JQ on Mac (El Capitan). The code is downloaded to my Mac but I would like to know how I can install and operate it via the command line.
