In Python, modules are accessed by using theimportstatement. When you do this, you execute the code of the module, keeping the scopes of the definitions so that your current file(s) can make use of these. When Python imports a module calledhellofor example, the interpreter will first searc...
Python's syntax allows for code to be significantly shortened by using something calledmodules.Similar to header files in C++, modules are a storage place for the definitions of functions. They are separated into common uses, such as the time module, which provides functions for time related use...
You can use the built-ineval()to evaluate arbitrary Python expressions from string-based or compiled-code-based input. This is a good option if you need to dynamically evaluate Python expressions. When you pass a string argument toeval(), it compiles it into bytecode and evaluates it as a...
Python imports modules using the "import" statement. A module can be imported in a variety of ways depending on how you want to access its functions, classes, or variables. Here are the different ways to import modules: Basic import: import module_name The above command imports the entire m...
Python provides a “locale” module that you can use to set the locale for your current program and then convert it. import locale locale.setlocale(locale.LC_ALL, 'en_US.UTF-8') data_str = "5,678" print(data_str) # Output: 1.23e4 print(type(data_str)) # Output: <class 'str'...
Python String is a sequence of characters. We can convert it to the list of characters using list() built-in function. When converting a string to list of characters, whitespaces are also treated as characters. Also, if there are leading and trailing whitespaces, they are part of the list...
In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
Theimportlib.reload()method is most often used when we have edited the source of the module using an external editor and we want to get access to the newer version without exiting the interpreter. Thereload()method returns the module object, so you can directly reassign the module to the re...
Converting Bytes to Strings: The .decode() Method A bytes object in Python is human-readable only when it contains readable ASCII characters. In most applications, these characters are not sufficient. We can convert a bytes object into a string using the .decode() method: data = bytes([68...
