We want to input age which should be greater than 18 and less than 51, gender which should be either "Male" or "Female". If the user inputs an invalid value, the program should ask again for the input.Input until a valid response ...
To use the program for another name and city, you can edit the code, change name to say "Ravi" and city to "Chennai". Every time you need to assign different value, you will have to edit the program, save and run, which is not the ideal way....
Python decorators allow you to wrap a function with another function to extend or modify its behavior without altering the original function’s code. Practical use cases for decorators include logging, enforcing access control, caching results, and measuring execution time. Custom decorators are ...
Time for a script again, this one will geolocate an IP address based on input from the user. For this script, we will be using a bunch of Python modules to accomplish this. Get the username from a prompts This script will ask the user for its username, by using the raw_input functio...
2. Open your preferred text editor and copy/paste the code below. Save the code as a Python script file (.py) with the name of your choice. But for this example, the text file is namedtext-writing.py. Running the code below asks a user for a text file name and its content, then...
如果你想知道一个对象及其引用的所有对象占用了多少内存,Python 核心开发者 Raymond Hettinger 为此编写了一个函数,你可以在code.activestate.com/recipes/577504-compute-memory-footprint-of-an-object-and-its-cont访问这个函数。 所以你不应该觉得创建一个新的列表而不是在迭代时修改原来的列表是在浪费内存。即使...
Built-in functions, such as help() to ask for help, min() to get the minimum value, print() to print an object to the terminal,… You can find an overview with more of these functions here. User-Defined Functions (UDFs), which are functions that users create to help them out; And...
