   • Python File Open

     File handling is an important part of any web application.

     Python has several functions for creating, reading, updating, and deleting files.

     File Handling

     The key function for working with files in Python is the open() function.

     The open() function takes two parameters; filename, and mode.

     There are four different methods (modes) for opening a file:

     "r" - Read - Default value. Opens a file for reading, error if the file does not exist

     "a" - Append - Opens a file for appending, creates the file if it does not exist

     "w" - Write - Opens a file...

   • Python File Open

     Open a File on the Server

     Assume we have the following file, located in the same folder as Python:

     demofile.txt

     Hello! Welcome to demofile.txtThis file is for testing purposes.Good Luck!

     To open the file, use the built-in open() function.

     The open() function returns a file object, which has a read() method for reading the content of the file:

     Example

     f = open("demofile.txt", "r")print(f.read())

     If the file is located in a different location, you will have to specify the file path, like this:

     Example

     Open a file on a different location:

     f open D...

   • Python File Write

     Write to an Existing File

     To write to an existing file, you must add a parameter to the open() function:

     "a" - Append - will append to the end of the file

     "w" - Write - will overwrite any existing content

     Example

     Open the file "demofile2.txt" and append content to the file:

     f = open("demofile2.txt", "a")f.write("Now the file has more content!")f.close()#open and read the file after the appending:f = open("demofile2.txt", "r")print(f.read())

     Example

     Open the file "demofile3.txt" and overwrite the content:

     f = open("demofile3.txt", "w")f.write Woops I have deleted the...

   • Python For Loops

     Python For Loops

     A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string).

     This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages.

     With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc.

     Example

     Print each fruit in a fruit list:

     fruits = ["apple", "banana", "cherry"]for x in fruits: print(x)

     The for loop does not require...

   What is a logging module in Python?

   • The main component of the logging module is something called the logger. You can think of the logger as a reporter in your code that decides what to record, at what level of detail, and where to store or send these records. To get a first impression of how the logging module and a logger work, open the Python standard REPL and enter the code below:

   • The Logging Module. The logging module in Python is a ready-to-use and powerful module that is designed to meet the needs of beginners as well as enterprise teams.
   • Basic Configurations. You can use the basicConfig(**kwargs) function to configure the logging: “You will notice that the logging module breaks PEP8 styleguide and uses camelCase naming conventions.
   • Formatting the Output. While you can pass any variable that can be represented as a string from your program as a message to your logs, there are some basic elements that are already a part of the LogRecord and can be easily added to the output format.
   • Classes and Functions. So far, we have seen the default logger named root, which is used by the logging module whenever its functions are called directly like this: logging.debug().
