In this video, you’ll practice list indexing and slicing. The elements of a list can be accessed by an index. To do that, you name the list, and then inside of a pair of square brackets you use an index number, like what I’m showing right here. That…
ExampleOpen Compiler # Input tuple givenTuple = ("Welcome", "this", "is", "TutorialsPoint", "Website", 10) # Slicing with start and stop values(indices) print('Tuple slicing from index 1 to index 6 :', givenTuple[1:6]) # Slicing with only stop values(indices) print("Tuple ...
Field access - This is direct field access using the index of the value, for example, [0] index is for 1st value, [1] index is for the 2nd value, and so on. Basic Slicing - Basic slicing is simply an extension of Python's basic concept of slicing to the n dimensions. In order ...
Slicing¶ To extract multiple values (or slices), the Python list slicing syntax can be used: header = raw_files[:16] # extract 16-byte headers from files in the batch If the start of the slice is omitted, the slice starts at 0. If the end is omitted, the slice ends at the ...

The mechanics behind indexing and slicing dataFrames is the same as indexing and slicing strings, which we will learn in this chapter. Indexing The characters of Python strings exist in specific locations; in other words, their order counts. The index is a numerical representation of where each...
