<u>Answer:</u>
<em>When system feasibility is being determined </em>
<u>Explanation:</u>
<em>Prototyping is the part of Requirement and Analysis phase. </em>It is the phase where the client and the development team sits and discuss about what the requirement is and show <em>a model of what are all the things which they could bring up the requirement as a software. </em>
So here, the prototyping is really essential to visually understand how the team has interpreted the requirement and how far it matches with the client. <em>All the other options stands invalid in the given context.</em>
Answer:
short_names = ['Gus', 'Bob','Zoe']
Explanation:
A list is a type of data structure in python that allows us to store variables of different types. Each item in a list has an index value which must be a integer value, and the items can be assessed by stating the index position. The syntax for creating and initializing a list is:
list_name = [item1, item2,item3]
- The name of the list (must follow variable naming rules)
- a pair of square brackets
- items in the list separated by commas.
The python code below shows the implementation of the solution of the problem in the question:
<em>short_names = ['Gus', 'Bob','Zoe']</em>
<em>print(short_names[0])</em>
<em>print(short_names[1])</em>
<em>print(short_names[2])</em>
The output is:
<em>Gus</em>
<em>Bob</em>
<em>Zoe</em>
Answer:
Enter time 1 HH:MM:SS8:5:22
Enter time 2 HH:MM:SS7:24:37
0:40:45
Explanation:
The program for above in Python is:
from datetime import datetime
s1 = input("Enter time 1 HH:MM:SS")
s2 = input("Enter time 2 HH:MM:SS")
Format1 = '%H:%M:%S'
tdiff = datetime.strptime(s1, Format1) - datetime.strptime(s2, Format1)
print(tdiff)
We are using the datetime class in datetime module for using strptime to find the difference between the two times.
