The body of a function must be indented.Define a function using def name(.params.).

Additive sequence of an array code#

Put code whose parameters change frequently in a function, then call it with different parameter values to customize its behavior.Nest loops to operate on multi-dimensional data.Zero, the empty string, and the empty list are considered false all other numbers, strings, and lists are considered true.X or Y is true if either X or Y, or both, are true.X and Y is only true if both X and Y are true.The bodies of the branches of conditional statements must be indented.Use if condition to start a conditional statement, elif condition to provide additional tests, and else to provide a default.Specify colors use (red, green, blue) triples, each component of which is an integer in the range 0.255.Use the ImageGrid class from the ipythonblocks library to create simple вЂњimagesвЂќ made of colored blocks.Use * in a pattern to match zero or more characters, and ? to match any single character.Use glob.glob(pattern) to create a list of files whose names match a pattern.Strings are immutable (i.e., the characters in them cannot be changed).Lists are mutable (i.e., their values can be changed in place).Lists are indexed and sliced in the same way as strings and arrays.Use len(thing) to determine the length of something that contains other values.

The body of a for loop must be indented.Use for variable in collection to process the elements of a collection one at a time.Use the pyplot library from matplotlib for creating simple visualizations.Use an(axis=0) or an(axis=1) to calculate statistics across the specified axis.Use an(), array.max(), and array.min() to calculate simple statistics.Use # some kind of explanation to add comments to programs.All the indexing and slicing that works on arrays also works on strings.Use low:high to specify a slice that includes the indices from low to high-1.

Use array to select a single element from an array.

The expression array.shape gives the shape of an array.

Use print(something) to display the value of something.

Variables are created on demand whenever a value is assigned to them.

Use variable = value to assign a value to a variable in order to record it in memory.

Use the numpy library to work with arrays in Python.

Import a library into a program using import libraryname.
