Answer:
Step-by-step explanation
Code:
print('Enter a title for the data: ')
title=input()
print('You entered:',title)
print('\nEnter the column 1 header:')
header1=input()
print('You entered:',header1)
print('\nEnter the column 2 header:')
header2=input()
print('You entered:',header2)
names = []
data = []
while(True):
print('\nEnter a data point (-1 to stop input):')
datapoint=input()
if(datapoint=="-1"):
break
countcomma=datapoint.count(',')
if(countcomma==0):
print('Output: Error: No Comma in string')
continue
if(countcomma>1):
print('Output: Error: Too many commas in input')
continue
spliting = datapoint.split(',')
is_int = True
try:
# convert to integer
int(spliting[1])
except ValueError:
is_int = False
# print result
if is_int:
data.append(spliting[1])
else:
print('Output: Error: Comma not followed by an integer')
continue
names.append(spliting[0])
print(title.rjust(33,' '))
print(header1.ljust(20,' '),'|',header2.rjust(23,' '))
print('----------------------------------------------')
for i in range(0,len(names)):
print(names[i].ljust(20,' '),'|',data[i].rjust(23,' '))
print('\n')
for i in range(0,len(names)):
star='*'
length=int(data[i])
rating=star*length
print(names[i].rjust(20,' '),rating)
Output:
PFA
