Pandas' syntax for mapping index values to relevant data is the same syntax Python uses to map dictionary keys to values. For example, if s is a Series, s['a'] will return the data point at index a. Unlike dictionary keys, index values are not guaranteed to be unique. If a Series uses the index value a for multiple data points, then s['a'] will ...
Comma-separated values (CSV) is a text file format that uses commas to separate values, and newlines to separate records. A CSV file stores tabular data (numbers and text) in plain text, where each line of the file typically represents one data record. Each record consists of the same number of fields, and these are separated by commas in the ...

Series with sequences of partial sums that converge to a value but whose terms could be rearranged to a form a series with partial sums that converge to some other value are called conditionally convergent series. Those that converge to the same value regardless of rearrangement are called unconditionally convergent series.

The digits in the "odd place-intervals", i.e. between digits 2 2n+1 and 2 2n+2 − 1 are not restricted and may take any value. This fractal has upper box dimension 2/3 and lower box dimension 1/3, a fact which may be easily verified by calculating N(ε) for = and noting that their values behave differently for n even and odd.
Spielberg wanted a moodier film noir lighting style like in The Informer (1935). In contrast, Slocombe wanted to make things brighter and used backlighting to create a greater depth of field; Spielberg preferred his changes. Slocombe often employed natural light, using solar position predictions to plot a scene's layout.
