The dffs Library

The dffs library is a Python library for data cleaning and preprocessing. It provides a collection of tools for reading, transforming, and validating structured data.

Installation

To install dffs, you must have Python and pip installed. Once you have these dependencies, you can install dffs via pip:

pip install dffs

Usage

dffs provides a range of modules that allow you to clean and preprocess your data. Here are some examples:

Validation

The validation module provides a range of functions for validating data, such as checking whether a string is a valid email or whether a number is within a certain range.

from dffs.validation import is_email

email = "example@example.com"
if is_email(email):
    print(f"{email} is a valid email address")
else:
    print(f"{email} is not a valid email address")

This will output:

example@example.com is a valid email address

Cleaning

The cleaning module allows you to clean your data by stripping whitespace, removing punctuation, converting to lowercase, and much more.

from dffs.cleaning import clean_text

text = "This is a sentence with punctuation!"
cleaned_text = clean_text(text)
print(cleaned_text)

This will output:

this is a sentence with punctuation

Transformation

The transformation module provides functions for transforming your data, such as converting a string to a datetime object or calculating the length of a string.

from dffs.transformation import calculate_length

text = "This is a sentence."
length = calculate_length(text)
print(f"The length of '{text}' is {length}.")

This will output:

The length of 'This is a sentence.' is 19.

Conclusion

dffs is a powerful library for data cleaning and preprocessing. With its comprehensive collection of tools, you can easily validate, clean, and transform your data, making it easier to work with and analyze.
