Python Built In Functions

Review built-in functions in the Python language. These are used in many programs.

Built-ins. A programming language's syntax is important. But often, the standard library (full of built-in types) is even more critical to program development.

Python functions. We figure out how to read programs by recognizing keywords and built-ins. Programs can be predicted. These functions make them meaningful.absallanyasciibinboolbytearraybytescallablechrclassmethodcompilecomplexdelattrdictdirdivmodenumerateevalexecfilterfloatformatfrozensetgetattrglobalshasattrhashhelphexidimportinputintisinstanceissubclassiterlenlistlocalsmapmaxmemoryviewminnextobjectoctopenordpowprintpropertyrangereprreversedroundsetsetattrslicesortedstaticmethodstrsumsupertupletypevarszip

Keywords. Python also provides keywords. Some constants, like True and False and None are also made available. Programs are composed of these parts.andasassertbreakclasscontinuedefdelelifelseexceptFalsefinallyforfromglobalifimportinislambdaNonenonlocalnotpassraisereturntryTruewhilewithyield

Modules. In Python programs we often invoke methods from modules. With the import and "from" statements we use these units of code.arrayasynciocollectionscsvdatetimegziphtml.parseritertoolsjsonmathnumpyospathresubprocesstextwraptimetimeiturllibxml

Errors. Here are some errors. In Python we end up with errors when something goes wrong. The name of the error indicates the kind of problem that occurred.AssertionErrorIndentationErrorIOErrorJSONDecodeErrorKeyErrorNameErrorSyntaxError

Algorithms. Here are custom methods. Algorithms are methods that describe how complex (or simple) problems are solved. We analyze and mutate many data sources.Algorithm: AnagramAlgorithm: Compound InterestAlgorithm: FibonacciAlgorithm: FrequenciesAlgorithm: MazeAlgorithm: PalindromeAlgorithm: PrimeAlgorithm: Word Count

Recursion. Many problems are solved with recursion. In a recursive algorithm, we can perform a brute-force search of all possibilities.Recursion

Compression. With the gzip module we can compress (and decompress) data. We can handle compression with external programs like 7-Zip or use only Python methods.Compression: 7-ZipCompression: GZIPCompression: PAQ

JIT compiler. With an advanced just-in-time compiler like PyPy, Python programs execute much faster. These new technologies are a clear win in the Python world.PyPy: pypy.org

An external page. For each function, an example is provided on the linked page. You may want to use your browser's find command to locate the keyword.Built-in Functions: Python.org

A review. In this language, we have many powerful features. Python is important in the world. As you become an expert in Python you will be able to develop many important things.
