<span>Computer design replaced (B) models draw or created by hand. Technology nowadays has a big contribution in terms of planning and designing a building or a structure without burning your eyebrow facing that paper and handling your pen. Computer designs are used to make the design more accurate and more precise compared to traditional hand drawn designs.</span>

Answer:
The Python code is given below with appropriate comments
Explanation:
#required method, assuming Volume class is defined and is accessible
def partyVolume(filename):
#opening file in read mode, assuming file exists
file=open(filename,'r')
#reading initial volume
initial=float(file.readline())
#creating a Volume object with initial volume
v=Volume(initial)
#looping through rest of the lines in file
for line in file.readlines():
#removing trailing/leading white spaces/newlines and splitting line by white
#space to get a list of tokens
line=line.strip().split(' ')
#ensuring that length of resultant list is 2
if len(line)==2:
#reading first value as direction (U or D)
dir=line[0].upper()
#reading second value as float value
value=float(line[1])
if dir=='U':
#turning volume up
v.up(value)
elif dir=='D':
#turning volume down
v.down(value)
#closing file, saving changes
file.close()
#returning volume
return v
