Python download and open file from internet

To do this, you can use the open function that comes built into Python. The function takes two arguments or parameters: one that accepts the file's name and another that saves the access mode. It returns a file object and has the following syntax:. If the file isn't in the same directory, you must mention the file's full path when writing the file name parameter.

For instance, to open an "example. Python has several access modes, and these modes govern the operations that you can perform on an open file. In other words, every access mode refers to how the file can be used when it's open differently. Access modes in Python also specify the position of the file handle.

You can think of the file handle as a cursor indicating from where the data must be read or written. That said, using the access mode parameter is optional, as seen in the previous examples. There are two other parameters you can use to specify the mode you want to open the file in. Python reads files in text mode by default, which is specified with the parameter "t. In contrast, using the binary mode "b" when using the open function returns bytes.

Binary mode is typically used when handling non-text files such as images and executables. Here are few examples of using these access modes in Python:. Besides having a cleaner syntax, the "with" statement also makes exception handling easier when working with file objects. It is considered best practice to use the with statement when working with files whenever applicable.

A significant advantage that using the with statement offers is that it automatically closes any files you've opened after the operation is complete. Thus, you don't have to worry about closing the file and cleaning up after performing any operation on a file.

To read a file using the with statement, you would write the following lines of code:. When the second line of code runs, all of the data stored in "example. If you wanted to write data to the same file, you would run the following code:. Reading a file in Python is straightforward — you must use the 'r' parameter or not mention a parameter at all since it is the default access mode. That said, there are other ways to read data from a file in Python.

For example, you could use the read size method built into Python to read the specified size of data. If you do not specify the size parameter, the method will read the file until its end. Let's assume that "example. This file has two lines. To read the file using the read method, you would use the following code:. All the archives of this lecture are available here.

So, we first scrape the webpage to extract all video links and then download the videos one by one. It would have been tiring to download each video manually. In this example, we first crawl the webpage to extract all the links and then download videos.

This is a browser-independent method and much faster! One can simply scrape a web page to get all the file URLs on a webpage and hence, download all files in a single command- Implementing Web Scraping in Python with BeautifulSoup This blog is contributed by Nikhil Kumar.
