Python username and password with 3 attempts

Just started python and racking my brains on this but can't seem to get it right.

print('Enter correct username and password combo to continue')
count=0
password=Hytu76E
username=bank_admin

while password!='Hytu76E' and username!='bank_admin' and count<4:
    username=input('Enter username: ') and password=input('Enter password: ')

    if password=='Hytu76E' and username=='bank_admin':
     print('Access granted')

    else:
        print('Access denied. Try again.')
        count-=1

syntax error, can't assign to operator on line 6 username=input.

Fixed the code to achieve what you are trying to do:

print('Enter correct username and password combo to continue')
count=0
while count < 3:
    username = input('Enter username: ')
    password = input('Enter password: ')
    if password=='Hytu76E' and username=='bank_admin':
        print('Access granted')
        break
    else:
        print('Access denied. Try again.')
        count += 1

Changes that have been made:

• Removed the definition of username and password since it is redundant and can be omitted
• Changed the while statement to count 3 iterations of count
• Validation of the credentials only in the if statement and not in the while
• Changed the decreasing of count to increasing (from count -= to count +=)
• break the loop when the right credentials are entered
