Python is a high-level, interpreted programming language created by Guido van Rossum and first released in 1991. It is designed with an emphasis on code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in languages such as C++ or...
Reading a file in Python is fast; for example, it takes roughly 0.67 seconds to write a 100MiB file. But if the file size exceeds 100 MB, it would cause memory issues when it is read into memory. ADVERTISEMENT Python has 3 built-in methods to read the specific lines from a file, ...
The function opens the file whose name is provided in its parameter. Then it applies thereadlines()method, which returns a Python list containing the lines of the file as its elements. That list is saved to thewordsvariable and returned by the function. ...
