Answer:
See explaination
Explanation:
def readFileFirstLast(filename):
# doc string
''' Function accept the filename and opens the fle
and reads all lines and strips new line character and
stores first and last in a string and return that string'''
#eception handle if file not found
try:
#opening the file
f = open(filename)
#reading the first line and striping the ne line
string = f.readline().strip()
#iterating until last line
for line in f:
pass
#concate the last line after strip the new line character to the string
string = string + " " + line.strip()
#return the string
return string
except:
#if file not found
return "File not found"
#taking the file name from user
filename = input("Enter a file name: ")
#printing the doc string in function
print("\ndoc_sting: \n"+ readFileFirstLast.__doc__+"\n")
#printing the returned string by calling the readFileFirstLast()
print("output string :")
print(readFileFirstLast(filename))
13? 13 is most minimum ages however, I don't understand this question all that well.
