python - operator.itemgetter or lambda - Stack Overflow

Leaving aside the speed issue, which is often based on where you make the itemgetter or lambda function, I personally find that itemgetter is really nice for getting multiple items at once: for example, itemgetter(0, 4, 3, 9, 19, 20) will create a function that returns a tuple of the items at the specified indices of the listlike object passed to it.

Working With the Python operator Module

Python built-in operators will outperform both the operator module’s versions and lambdas, while the operator functions will outperform lambdas. If you make a single call to a lambda or the operator module equivalent, then you won’t notice much difference. However, when you make repeated calls, the difference becomes significant. The

python - "lambda" vs. "operator.attrgetter('xxx')" as a sort key ...

i concur with alex's answer (that's he's no lambda lover) :-) but also second the notion of the lambda. in your example above, it may be a tiny bit faster because you don't have to look up either operator or operator.attrgetter()... you have the actual function object already! however, it is barely noticeable as alex has said already, but the lambda solution does win Python Zen points by being ...

What is the difference between these two solutions - lambda or loop ...

lambda is used for when you need to pass a short function to something, and that function is just a basic transformation on inputs. For instance, some of the sort functions in the Python library allow you to pass a function to them to compare two items, if you want to sort a list in a non-standard way perhaps - then you could use something like lambda x,y: <comparison between x and y here>.

what is the difference for python between lambda and regular function ...

Both lambda and def create the same kind of function – they have the same kind of metadata and capabilities. Their technical difference is syntactical:. A lambda is an expression producing a function.; A def is a statement producing a function.; This is everything that dictates how they can be used.Other apparent differences simply come from the information lambda/def can capture.

lambda in python - Stack Overflow

My problem concerns lambda in python : Can i define a general function in python with an operator as one of the arguments? Think this : def f (op,x,y): #return some lambda function that combines x and y in the appropriate way #i.e if op is +, then return x+y, if op is -, then return x-y etc #Edit : added usage #this should be called like this: f(+, 1,2) #should return 3 I know this is possible ...

python - Use of AND & OR in the same LAMBDA function - Stack Overflow

In Python every object can be tested for its boolean value - I highly recommend reading the linked Python official documentation section. Python and and or operators not only evaluate the expression, but also return one of the operands based on the Boolen value:. and returns the second operand if the first evaluates to True; otherwise the first operand (evaluated to False) is returned.

6. Expressions — Python 3.13.3 documentation

Conditional expressions (sometimes called a “ternary operator”) have the lowest priority of all Python operations. The expression x if C else y first evaluates the condition, C rather than x. If C is true, x is evaluated and its value is returned; otherwise, y is evaluated and its value is returned. See PEP 308 for more details about conditional expressions. 6.14.
