SOS HELP!!! Please use Python code to do. Thank you so much.
Q1:
Write a program that asks a user to read in a file name and then open the file. If filename is wrong, user could re-enter (no limit). Once a file opened, read in line by line to a list. Print the list and then close the file. For example, if the file contains
Hello All
This is our last test
Good luck
Your program will print out ["Hello All", "This is our last test", "Good luck"]
Q2:
Given the code below, answer questions (a) to (d)
try :
inFile = open("test.txt", "r")
line = inFile.readline() #line A
value = float(line) #line B
print("A")
except IOError :
print("B")
except ValueError :
print("C")
else:
print("D")
finally:
print("E")
- What output is generated when this program runs if test.txt is not opened successfully?
- What output is generated when this program runs if test.txt is opened successfully and no additional exception occurs?
- What output is generated when either line A or line B would have exceptions?
- What output is generated when only line B raises exception?
Q3:
We have a list of scores, say [50, 35, 45, ...], write code to store the scores in a text file "scores.txt", one score per line, e.g.
50
35
45
...
(no need to handle exception. If scores.txt aleady exist, you may wipe out the content,.)
