python actually supports huge number of file types nativelyand libraries that provide additional support are available if you have file type that you need to support using pythonyou can usually find third-party library to support it when python doesn' support it natively unfortunatelyno comprehensive list of supported files existsso you need to search online to find how python supports the file you need the documentation divides the supported files by types and doesn' provide comprehensive list for exampleyou can find all the archive formats at html and the miscellaneous file formats at org/ /library/fileformats html type the following code into the window at the end of the existing code -pressing enter after each linedef savedata(filename ""datalist [])with open(filename" "newline='\ 'as csvfiledatawriter csv writercsvfiledelimiter='\ 'quotechar="quoting=csv quote_nonnumericdatawriter writerow(datalistcsvfile close(print("data saved!"make absolutely certain that savedata(is properly indented if you add savedata(to the file but don' indent it under the formatdata classpython will treat the function as separate function and not as part of formatdata the easiest way to properly indent the savedata(function is to follow the same indentation used for the __init__(and __str__(functions notice that the method accepts two arguments as inputa filename used to store the data and list of items to store this is class method rather than an instance method later in this procedureyou see how using class method is an advantage the datalist argument defaults to an empty list so that if the caller doesn' pass anything at allthe method won' throw an exception insteadit produces an empty output file of courseyou can also add code to detect an empty list as an errorif desired the with statement tells python to perform series of tasks with specific resource -an open csvfile named testfile csv the open(function accepts number of inputs depending in how you use it for this exampleyou open it in write mode (signified by the wthe newline attribute tells python to treat the \ control character (linefeedas newline character
