Well, tonight I have installed the NDB which if you work with back end nodejs stuff you should be familiar with, in order to debug and fix the problems inside our server codes.
Establishing a Back-End system with nodejs is really straight forward and not that complex but the problem is to secure, authenticate, validate and handle the errors of the data flow inside the system which is really mind blowing and complex to do.
Tonight I got really confused but I have to figure it all out and I will!
Trying to finish my SQL labs for school. I’m a little stuck but it’s mostly basic stuff I am working on so I’m sure I’ll figure it out. I have to add 2 columns together without using the alias column names.
Where func is the function on which each element in iterables (as many as they are) would be applied on. Notice the asterisk(*) on iterables? It means there can be as many iterables as possible, in so far func has that exact number as required input arguments.
While map() passes each element in the iterable through a function and returns the result of all elements having passed through the function, filter(), first of all, requires the function to return boolean values (true or false) and then passes each element in the iterable through the function, "filtering" away those that are false. It has the following syntax:
f = [6, -7, 1, -9, 0, 2, -5]
result = list(filter(lambda x: x < 0, f))
# [-7, -9, -5]
reduce applies a function of two arguments cumulatively to the elements of an iterable, optionally starting with an initial argument. It has the following syntax:
