Methods

Method	Description	Parameters	Returns
`decode_base64`	Decodes a base64 encoded string.	`encoded_text (str)` The base64 encoded string to decode.	`str` The decoded string.
`encode_base64`	Encodes a string to base64.	`text (str)` The string to encode.	`str` The base64 encoded string.
`get_char_and_ascii_number_pairs`	Returns a list of tuples containing the character and its ASCII number.	`text (str)` The string to analyze.	`list[tuple[str, int]]` A list of tuples containing the character and its ASCII number.
`get_emails`	Returns a list of email addresses found in a string.	`text (str)` The string to search for email addresses.	`list[str]` A list of email addresses found in the string (without duplications).
`get_last_char`	Returns the last character of a string.	`text (str)` The string to analyze.	`str` The last character of the string.
`get_urls`	Returns a list of URLs found in a string.	`text (str)` The string to search for URLs.	`list[str]` A list of URLs found in the string (without duplications).
`is_decimal`	Checks if a string is a decimal number.	`text (Optional[str])` The string to check.	`bool` True if the string is a decimal number, False otherwise.
`is_int`	Checks if a string is an integer.	`text (Optional[str])` The string to check.	`bool` True if the string is an integer, False otherwise.
`is_json`	Checks if a string is a valid JSON.	`text (Optional[str])` The string to check.	`bool` True if the string is a valid JSON, False otherwise.
`is_positive_decimal`	Checks if a string is a positive decimal number.	`text (Optional[str])` The string to check.	`bool` True if the string is a positive decimal number, False otherwise.
`is_positive_int`	Checks if a string is a positive integer.	`text (Optional[str])` The string to check.	`bool` True if the string is a positive integer, False otherwise.
`is_unsigned_decimal`	Checks if a string is an unsigned decimal number.	`text (Optional[str])` The string to check.	`bool` True if the string is an unsigned decimal number, False otherwise.
`is_unsigned_int`	Checks if a string is an unsigned integer.	`text (Optional[str])` The string to check.	`bool` True if the string is an unsigned integer, False otherwise.
`remove_extra_spaces`	Removes extra spaces from a string.	`text (str)` The string to process. `is_remove_end_of_line (bool, Default: False)` If set to True, the function will treat newline characters (e.g., \n, \r) as extra spaces and remove them, effectively joining all lines into a single continuous line of text`	`str` A text without extra spaces
`replace`	Multiple string replacement.	`text (str)` The original string. `replacements (dict[str, str])` A dictionary where keys are substrings to be replaced and values are their replacements.	`str` The modified string after replacements.
`sub_string`	Returns a substring from a string.	`text (str)` The string to extract the substring from. `start_delimiter (str)` Sub string start delimiter. `end_delimiter (Optional[str])` Sub string end delimiter.	`str` The extracted substring.
`sub_string_list`	Returns a list of substrings from a string.	`text (str)` The string to extract the substrings from. `start_delimiter (str)` Sub string start delimiter. `end_delimiter (Optional[str])` Sub string end delimiter.	`list[str]` A list of extracted substrings.
`to_ascii`	Converts a string to ASCII.	`text (str)` The string to convert.	`str` The ASCII representation of the string.

Examples:

StringUtil.decode_base64

Code

from string_utils import StringUtil

# Decode a base64 encoded string
decoded_text = StringUtil.decode_base64('dGVzdA==')
print(decoded_text)

Output

test

StringUtil.encode_base64

Code

from string_utils import StringUtil

# Encode a string to base64
encoded_text = StringUtil.encode_base64('test')
print(encoded_text)

Output

dGVzdA==

StringUtil.get_char_and_ascii_number_pairs

Code

from string_utils import StringUtil

# Get the character and its ASCII number pairs
pairs = StringUtil.get_char_and_ascii_number_pairs('test')
print(pairs)

Output

[('t', 116), ('e', 101), ('s', 115), ('t', 116)]
