Furthermore, the Heirloom Project Development Tools includes a free version of the m4 language, derived from OpenSolaris. M4 has been included in the Inferno operating system. This implementation is more closely related to the original m4 developed by Kernighan and Ritchie in Version 7 Unix than its more sophisticated relatives in UNIX System V ...
However, if data is a DataFrame, then data['a'] returns all values in the column(s) named a. To avoid this ambiguity, Pandas supports the syntax data.loc['a'] as an alternative way to filter using the index. Pandas also supports the syntax data.iloc[n], which always takes an integer n and returns the nth value, counting from 0. This allows a ...
The difference is an exact number of quarters of an hour up to 95 (same minutes modulo 15 and seconds) if the file was transported across zones; there is also a one-hour difference within a single zone caused by the transition between standard time and daylight saving time (DST). Some, but not all, file comparison and synchronisation software ...
