Alternative to classic input with support for restricting certain characters
Project description
Restricted Input
Important Change
Made a small backward incompatible change. Instead of exclude
, use allow
. I changed it because:
- There was a typo anyway. It was
exlude
instead ofexclude
! - I feel like
allow
has a better and clearer meaning thanexclude
.exclude
might be confusing sometimes.
Overview
A way of imposing restrictions in input()
.
For example, if you want the user to only enter numbers, you could use this. Only want uppercase letters? Works here.
It uses msvcrt.getch/alternative in *nix to get the keystroke and check it in real time.
Installation
Install restricted_input from pypi using:
pip install restricted_input
How to use it
Import it
from restricted_input import r_input
r_input
is the function which can be used instead of input()
It has five arguments
variable = r_input(prompt, input_type, allow, maxlength, warning)
-
prompt
: is the prompt to be given for the input dialog.string
-
input_type
: is the type of data to which the input should be restricted to.string
It can be
-
"normal"
: normal text -
"string_all"
: Allows only string, space is not allowed -
"string_upper"
: Allows only uppercase string, space is not allowed -
"string_lower"
: Allows only lowercase string, space is not allowed -
"specials"
Allows only special characters - `` ~ ! @ # $ % ^ & * ( ) - _ = + [ { ] } ; : ' " , < . > / ? \ |`. Space not included -
"integer"
: Allows only integers, doesn't allow-
,.
or space -
"float"
: Allows only integers, including.
single time. Space or-
not included -
"version"
: Allows only integers, including.
multiple times. Space or-
not included -
"nothing"
. Obviously allows nothing. Useful in scenarios where you need only a limited number of characters.
To get the list of input_types:
from restricted_input import get_input_types print(get_input_types)
-
-
allow: is the argument for allowing certain characters.
string or list
For example, if you want to allow hyphens in
integers
, you can user_input("Enter the number: ", "integer", "-")
If you want to allow input of the character
v
,a
,b
andg
in version type input, use:r_input("Enter the version: ", "version", "vabg") # Or r_input("Enter the version: ", "version", ["v", "a", "b", "g"])
-
maxlength
: is the argument for maximum length for input. Useful in scenarios where only single character is required.integer
-
warning
: is the argument for any warnings is the user has entered something which isn't allowed.string
Example
Issues/limitations
-
It will not work in some IDLEs like Spyder or PyCharm. This is because some IDLEs emulate a terminal which might not work with this module. Try to run the program in external terminal.
