Python: syntax assignment error in iteration

I am doing a simple script for self learning in python where the scripts in turn finds the 1000th prime number but I get a syntax error. 

x = 0
y = 2
counter = x
integer = y
while (counter>999):
      if (y%2 == 0 or y%3 == 0):
          y = y + 1
      else:(counter = counter + 1 and integer = integer + 1)
print (y)

when it comes to the ='s assignment right after the ELSE operator and I don't understand why it won't let me add one to both the counter and integer when this has worked in other iteration scenario

In python, assignment to variable has no Boolean value. and mean Boolean operator not do this and this.

so you need to split the statements. 

x = 0
y = 2
counter = x
integer = y
while (counter>999):
    if (y%2 == 0 or y%3 == 0):
        y = y + 1
    else:
        counter += 1
        integer += 1
print (y)

In python you can't make an assignment inside an expresion, to avoid misspellings between = and ==. So you must do that in two lines:

x = 0
y = 2
counter = x
integer = y
while (counter>999):
    if (y%2 == 0 or y%3 == 0):
        y = y + 1
    else:
        counter += 1
        integer += 1
print (y)

try this

   else:
      counter = counter + 1
      integer = integer + 1
