The ‘#’ option causes the “alternate form” to be used for the conversion. The alternate form is defined differently for different types. This option is only valid for integer, float, complex and Decimal types. For integers, when binary,octal, or hexadecimal output is used, this option a...

It determines the type of conversion that Python applies to the corresponding value before inserting it into the format string. Here’s a table that lists the possible conversion types: <type>Conversion Type d, i, u Decimal integer x, X Hexadecimal integer o Octal integer f, F Floating-point...
To interpolate values into a string template using .format(), you can use positional arguments in the method call. You can then use integer indices to determine which replacement field to insert each value into:Python 👇 👇 👇 >>> print("{0} {1} cost ${2}".format(6, "bananas...

Python Unlike JavaScript, we cannot concatenate an integer to a string in Python, otherwise we’ll get a TypeError: can only concatenate str (not “int”) to str. Therepr()method Similar tostr(), we userepr()to get a string representation of an object. Typically, therepr()returns a st...
