I need to have try-except structures to deal with any errors that may occur (which will most likely be an unreadable file path) in the functions of my code.

Here's what I have so far:

def writeToTextFile(filename, line):

with open(filename, 'a') as outfile:

outfile.write(line)

outfile.write(' ')

print('Line appended to file successfully.')

def readFromTextFile(filepath):

try:

file_contents = ''

with open(filepath, 'r') as infile:

for line in infile:

file_contents += line.strip() + ' '

return file_contents.lstrip()

except:

print('Error: could not open/read file')

return None

def readListFromTextFile(filepath):

try:

file_contents = []

with open(filepath, 'r') as infile:

for line in infile:

file_contents.append(line.strip())

return file_contents

except:

print('Error: could not open/read file')

return None

def main():

while True:

print('[1] Append to File')

print('[2] Read File Contents')

print('[3] Read File as List')

print('[4] Exit')

choice = input('Enter your choice: ')

if choice == '1':

filepath = input('Enter file path: ')

line = input('Enter line to append: ')

writeToTextFile(filepath, line)

elif choice == '2':

filepath = input('Enter file path: ')

lines = readFromTextFile(filepath)

print('File Contents:')

if lines is not None:

print(lines)

elif choice == '3':

filepath = input('Enter file path: ')

line_list = readListFromTextFile(filepath)

if line_list is not None:

print(line_list)

elif choice == '4':

break

print('Bye.')

if __name__ == '__main__':

main()
