Some Understanding of return and print in python, pythonreturnprint Preface I recently started to learn python. I only had some c basics and I forgot about it. Now I want to learn and share my ideas ~ I read the return usage while reading the book, but it is mixed with print later. I always feel that the return value of the function can be directly displayed, but this is not the case. Next, let's take a look at the understanding of return and print in python. Let's take a look at the detailed in

anonymous function lambdaLambda Argument1,argument2,... argumentn:expression using arguments1, Lambda is an expression, not a statement.Because of this, lambda can appear where the DEF is not allowed in the Python syntax---for example, in a list constant or in the parameters of a function call.2. The body of a lambda is a single expression, not a block of code.Lambda is designed for writing simple functions, and DEF is used to handle larger tasks.For example:Lambda notation:F=lambda X,y,z:x+y+

If object is a code object, it is simply executed. Globals: An optional parameter that represents the global namespace (which holds the global variable) and, if provided, a Dictionary object.
