Python ‘readline’
Python ‘readline’:
The readline module in Python is part of the standard library and provides a way to interact with the underlying command-line interface of your operating system, enabling features like line editing, history browsing, and autocompletion. However, it is a Unix-specific library, which means it’s only available on Unix-like systems such as Linux and MacOS.
If you just want to read a line from a file, you can do it as follows:
with open('file.txt', 'r') as file:
line = file.readline()
print(line)
Here is a basic example of how you might use the readline module:
import readline
def completer(text, state):
options = [i for i in commands if i.startswith(text)]
if state < len(options):
return options[state]
else:
return None
commands = ['first', 'second', 'third', 'fourth', 'fifth']
readline.parse_and_bind("tab: complete")
readline.set_completer(completer)
while True:
cmd = input("Command: ")
print("You entered: ", cmd)
In this example, the readline module is used to provide autocompletion for a simple command-line interface. When the user presses the tab key, the input they’ve provided so far is completed to the nearest match in the commands list. If no match is found, the input is unchanged.
Note: If you are working on Windows, the readline module is not available in the standard library. You can use the pyreadline module, which is a separate, Python-only implementation of readline, designed to be used on Windows systems.
