Given the list of customer segments below please create a new list of the names of the segments only using(a) a for loop(b) a list comprehension(c) a map().List would look something like ['Wallstreet','Gambler','Parents'] but of course using each tool as listed:segments = [{'name': 'Wallstreet', 'average_spend': 82.01}, {'name': 'Gambler', 'average_spend': 107.00}, {'name': 'Parents', 'average_spend': 10.52}]
Answer:
new_segment = [ ]
for segment in segments:
new_segment.append({'name': segment, 'average_spend': money})
print( new_segment)
Using list comprehension:
new_segment =[{'name': segment, 'average_spend': money} for segment in segments]

A computer has 38 address lines. How many locations in Mega bytes can it address?
Answer:
The computer can address 34359,738368 megabytes
Explanation:
Given
Address Lines (n) = 38
Required
Determine the number of location it can address
Number of addressable locations (N) in bits is calculated as thus
[tex]N = 2^n.[/tex]
Substitute 38 for n
[tex]N = 2^{38}[/tex]
[tex]N = 274877906944\ bits[/tex]
Next; is to convert from bits to megabytes
Start by converting to bytes
1 bit = 0.125 bytes;
So;
[tex]N = 274877906944 * 0.125\ bytes[/tex]
[tex]N = 34359738368\ bytes[/tex]
Convert from byte to megabyte
[tex]1\ byte = 10^{-6}\ megabyte[/tex]
So;
[tex]N = 34359738368\ * 10^{-6}\ MB[/tex]
[tex]N = 34359,738368\ MB[/tex]
Hence, the computer can address 34359,738368 megabytes
