operator — Standard operators as functions — Python 3.13.3 documentation
The operator module also defines tools for generalized attribute and item lookups. These are useful for making fast field extractors as arguments for map(), sorted(), itertools.groupby(), or other functions that expect a function argument. operator. attrgetter (attr) ¶ operator. attrgetter (* attrs) Return a callable object that fetches attr from its operand.

Python Operators - GeeksforGeeks
Python Arithmetic operators are used to perform basic mathematical operations like addition, subtraction, multiplication and division. In Python 3.x the result of division is a floating-point while in Python 2.x division of 2 integers was an integer.

10.3. operator — Standard operators as functions - Python 3.7 Documentation
10.3.2. Inplace Operators. Many operations have an “in-place” version. Listed below are functions providing a more primitive access to in-place operators than the usual syntax does; for example, the statement x += y is equivalent to x = operator.iadd(x, y).Another way to put it is to say that z = operator.iadd(x, y) is equivalent to the compound statement z = x; z += y.

6. Expressions — Python 3.13.3 documentation
The | operator yields the bitwise (inclusive) OR of its arguments, which must be integers or one of them must be a custom object overriding __or__() or __ror__() special methods. 6.10. Comparisons¶ Unlike C, all comparison operations in Python have the same priority, which is lower than that of any arithmetic, shifting or bitwise operation.

Built-in Types — Python 3.13.3 documentation
Operations and built-in functions that have a Boolean result always return 0 or False for false and 1 or True for true, unless otherwise stated. (Important exception: the Boolean operations or and and always return one of their operands.) Boolean Operations — and, or, not ¶ These are the Boolean operations, ordered by ascending priority:

5. Data Structures — Python 3.13.3 documentation
Note that in Python, unlike C, assignment inside expressions must be done explicitly with the walrus operator:=.This avoids a common class of problems encountered in C programs: typing = in an expression when == was intended.. 5.8.

string — Common string operations — Python 3.13.3 documentation
vformat (format_string, args, kwargs) ¶. This function does the actual work of formatting. It is exposed as a separate function for cases where you want to pass in a predefined dictionary of arguments, rather than unpacking and repacking the dictionary as individual arguments using the *args and **kwargs syntax. vformat() does the work of breaking up the format string into character data and ...
