The triangle indicates that the clock signal is an edge-triggered signal.
The circle indicates that the signal is low-active (ie., inverted).
The 74LS74 has a positive-edge trigger clock (low to high).

Write a function that will sum all of the numbers in a list, ignoring the non-numbers. The function should takes one parameter:
olasank [31]

In python 3.8:

def func(value_list):

   lst = [x for x in value_list if type(x) == int or type(x) == float]

   return sum(lst)

print(func(["h", "w", 32, 342.23, 'j']))

This is one solution using list comprehensions. I prefer this route because the code is concise.

def func(value_list):

   total = 0

   for x in value_list:

       if type(x) == int or type(x) == float:

           total += x

   return total

print(func(["h", "w", 32, 342.23, 'j']))

This is the way as described in your problem.

Answer:

By supplying a variety of charts and graphs to present the information in best way.

By tracking and analyzing the data

By conveying large amount of numerical data in more understandable format.

Explanation:

You need to know the limitations of Excel software. You will find that it does not support more than 3 variables while analyzing. However, if you use analytic software like Tableau and Microsoft Power BI then you can use a lot number of variables. And this is done through graphs and charts, and the other variables apart from x, y, z are the colors, shades. etc. Even color alone can add a good number of variables, and hence you can understand. Thus, you will be able to query better. Queries become better if you have more variables. And charts and graphs always present the information in the best way/ Also you can track and analyze the data. And through it conveying a large amount of numerical data in a more understandable format is made possible, and this is definitely quite helpful. Hence, all of the options mentioned above are helpful. But they do not do complex calculations and complex queries in fact.
