This method shuffles the given string or an array. It randomizes the items in the array. This method is present in the random module. So, we need to import it and then we can call the function. It shuffles elements each time when the function calls and produces different output. import random list = [12,25,15,65,58,14,5,]; …
You have to import CGI module to access form fields using FieldStorage class. Attributes of class FieldStorage for the form: form.name: The name of the field, if specified. form.filename: If an FTP transaction, the client-side filename. form.value: The value of the field as a string. form.file: file object from which data read. form.type: The content …
The Python provides libraries/modules that enable you to manipulate text files and binary files on the file system. It helps to create files, update their contents, copy, and delete files. The libraries are os, os.path, and shutil. Here, os and os.path – modules include a function for accessing the filesystem while shutil – module enables …

Python 2.x is an older version of Python. Python 3.x is newer and latest version. Python 2.x is legacy now. Python 3.x is the present and future of this language. The most visible difference between Python2 and Python3 is in print statement (function). In Python 2, it looks like print “Hello”, and in Python 3, …

You have to define an alias for the base class, assign the real base class to it before your class definition, and use the alias throughout your class. You can also use this method if you want to decide dynamically (e.g., depending on availability of resources) which base class to use. Example BaseAlias = <real base class> …

In Python 3, the old Unicode type has replaced by “str” type, and the string is treated as Unicode by default. We can make a string in Unicode by using art.title.encode(“utf-8”) function.
In Python, some amount of coding is done at compile time, but most of the checking such as type, name, etc. are postponed until code execution. Consequently, if the Python code references a user-defined function that does not exist, the code will compile successfully. The Python code will fail only with an exception when the …

Memory is managed in Python by the following way: The Python memory is managed by a Python private heap space. All the objects and data structures are located in a private heap. The programmer does not have permission to access this private heap. We can easily allocate heap space for Python objects by the Python …
The shortest way to open a text file is by using “with” command in the following manner: with open(“file-name”, “r”) as fp: fileData = fp.read() #to print the contents of the file print(fileData)
