inp_kwargs

Easily validate user inputs with Python, no hassle required!

A Python library for easy input validation using kwargs. This library helps to easily validate inputs such as integers, strings, and more, without needing to write complex validation logic. Additionally, these functions prevent the program from crashing due to invalid inputs, ensuring a robust and user-friendly experience.

Example

Validating an Integer Input

from inp_kwargs import input_int

# Basic integer validation
# Ensures the program won't crash even if the user enters invalid data (e.g., a string).
test = input_int("Enter a number: ")
print(f"You entered: {test}")

# Request a number between 1 and 100
number = input_int("Enter a number between 1 and 100: ",
                   min_value=1,
                   max_value=100)

print(f"You entered: {number}")

# Request a number with custom error messages
number = input_int("Enter a number: ",
                   min_value=1,
                   max_value=100,
                   min_value_error_message="Error: Must be >= 1.",
                   max_value_error_message="Error: Must be <= 100.")
print(f"You entered: {number}")

Available Functions

1. input_int

Validate integer inputs with customizable criteria.

Parameters:

• min_value (int, optional): Minimum value allowed.
• max_value (int, optional): Maximum value allowed.
• range (list, optional): Restrict input to a specific range of values.
• allowed_values (list, optional): Accept only specific values.
• even (bool, optional): Ensure the number is even.
• odd (bool, optional): Ensure the number is odd.
• multiple_of (int, optional): Validate input is a multiple of the given number.
• type_error_message (str, optional): Error message for invalid type.
• clear_console (bool, optional): Clears the console after each invalid input.

Example:

from inp_kwargs import input_int

number = input_int("Enter a number: ", min_value=1, max_value=10, even=True)
print(f"Validated number: {number}")

2. input_float

Validate float inputs with customizable criteria.

Parameters:

Similar to input_int, but for float values.

Example:

from inp_kwargs import input_float

number = input_float("Enter a decimal number: ", min_value=0.5, max_value=9.9)
print(f"Validated float: {number}")

3. input_str

Validate string inputs with customizable criteria.

Parameters:

• strip (bool, optional): Remove leading and trailing spaces.
• min_length (int, optional): Minimum string length.
• max_length (int, optional): Maximum string length.
• allowed_characters (str, optional): Restrict characters in input.
• pattern (str, optional): Validate input using a regex pattern.
• clear_console (bool, optional): Clears the console after each invalid input.
• strip_error_message (str, optional): Message when string is empty after trimming.
• min_length_error_message (str, optional): Error message for short strings.
• max_length_error_message (str, optional): Error message for long strings.

Example:

from inp_kwargs import input_str

text = input_str("Enter a word: ", min_length=3, max_length=8, strip=True, allowed_characters="abcdefghijklmnopqrstuvwxyz")
print(f"Validated string: {text}")
