F-strings are a powerful and easy-to-use way to format strings in Python. They are more readable than traditional string formatting methods and offer more flexibility. In this blog post, we will explore five useful F-string formatting tricks that you can use to make your code more readable and maintainable. Use f-string to format number: You can insert any character after the colon in an f-string to add them as thousand separators....

The Python calendar module defines the Calendar class. This is used for various date calculations as well as TextCalendar and HTMLCalendar classes with their local subclasses, used for rendering pre formatted output. Import the module: import calendar Print the current month: import calendar year = 2016 month = 1 cal = calendar.month(year, month) print(cal) The output will look like this: January 2016 Mo Tu We Th Fr Sa Su 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Set the first day of the week as Sunday:...

Similar to the int data type, floats also have several additional methods useful in various scenarios. For example, you can directly check if the float number is actually an integer with is_integer(): >>> (5.9).is_integer() False >>> (-9.0).is_integer() True Integer values might be preferred over floats in some cases and you can convert a float to a tuple matching a fraction with integer values: >>> (-5.5).as_integer_ratio() (-11,2) # -11 / 2 == -5....

Python’s textwrap module is useful for rearranging text, e.g. wrapping and filling lines. Import the module: import textwrap Wrap the text in the string “parallel”, so that all lines are a maximum of x characters long: # When x = 2 textwrap.wrap("parallel", width=2) # Output: # ['pa', 'ra', 'll', 'el'] # When x = 4 textwrap.wrap("parallel", width=4) # Output: # ['para', 'llel'] Returns a list of lines (without trailing newlines)....

Python’s self explanatory module called unicodedata provides the user with access to the Unicode Character Database and implicitly every character’s properties. Lookup a character by name with lookup: >>> import unicodedata >>> unicodedata.lookup('RIGHT SQUARE BRACKET') ']' >>> three_wise_monkeys = ["SEE-NO-EVIL MONKEY", "HEAR-NO-EVIL MONKEY", "SPEAK-NO-EVIL MONKEY"] >>> ''.join(map(unicodedata.lookup, three_wise_monkeys)) '🙈🙉🙊' Get a character’s name with name: >>> unicodedata.name(u'~') 'TILDE' Get the category of a character: >>> unicodedata.category(u'X') 'Lu' # L = letter, u = uppercase Also, using the unicodedata Python module, it’s easy to normalize any unicode data strings (remove accents, etc):...
