Explanation:
The Java class "Password" is used by the program to make an instance of the password object and check its validity with the passwordChecker method defined within the Password class.

In Python, assume that a file containing a series of integers is named numbers.txt and exist on the computer's disk. Write a program that reads the entire numbers store in the file and calculates their total.
Here is what I have written but it does not run:
def. main():
out file=open('numbers.txt','r')
temp=outfile.readline()
total=0
while temp!='':
t=int(temp)
total=total+i
temp=outfile.readline()
outfile.close()
print('Total sum is:',total)
main()
Text file is a file named numbers.txt with the numbers 1-50 in it
