Answer:
- m = 3
- n = 20
-
- triList = []
- current = 0
- for i in range(1, n + 1):
- current = current + i
- if(current >= m and current <= n):
- triList.append(current)
-
- print(triList)
Explanation:
The solution code is written in Python 3.
Firstly, create variable m and n and set the value 3 and 20 to the variables (Line 1 -2)
Create a triangle number list (Line 4) and another variable current to hold the value of current total of triangle number (Line 5).
Create a for loop and iterate through the number between m and n (Line 6). Calculate the current total of triangle number (Line 7) and proceed to check if the current triangle number is bigger or equal to m and smaller and equal to n, add the current triangle number to triList (Line 8-9).
Print the triList (Line 11) and we shall get [3, 6, 10, 15]
Answer:
a. grep 'b[au]nk$' myLine
Explanation:
grep is a command used for searching a specified pattern in a given text.
Our goal is to match the character sequence - bank or bunk at the end of line in a given line referenced by myLine.
The regular expression for the specified match criterion is:
b[au]nk$
The second character can be either a or u.
$ indicates match at end of line.
So the overall grep command is :
grep 'b[au]nk$' myLine
Answer:
a)
Explanation:
Since the worksheet contains most of the data that you need, there is a decent possibility that it also contains the data that you are missing. Therefore, you should check for data you have previously hidden. Sometimes, some data in a worksheet may become irrelevant in a given moment, and instead of deleting it since it may be useful later most people tend to make that data hidden. So checking for previously hidden data may be the best solution in this scenario.
Answer:
Option 2: Variable names can not begin with a number.
Explanation:
As given Mark and John named a variable as 24_hour_mart while writing a program in python.
While it is forbidden to name a variable starting with any digit, only alphabets (capital and smaller) and underscore can be the first letter of the variable name.
Moreover, by considering the other options given:
- Variable name can include the underscore (_) between the words. It is used instead of spaces that are not allowed.
- There is no upper limit for variable length, it can be of any reasonable length and more than 10 characters say 11 or 12 are reasonable.
- There is no lower limit for variable length, it can be any reasonable length , even it can be of 1 character.
Variables named in python language must not be the keywords as they are reserved for other purposes.
i hope it will help you!
