print(x, y, z, w) В вашем коде ошибка синтаксиса возникает из-за отсутствия закрывающей скобки в условии if.
Обратите внимание на добавление закрывающей скобки перед двоеточием в строке с if.

Code Breakdown:
Python
print("x y z w") # Print header for output
for x in 0, 1: # Loop through x (0 and 1)
for y in 0, 1: # Loop through y (0 and 1)
for z in 0, 1: # Loop through z (0 and 1)
for w in 0, 1: # Loop through w (0 and 1)
if ((w or (not(x))) and (w == (not(y)) and (w <= z)) == 1:
print(x, y, z, w) # Print if condition is met
Use code with caution.
Error Explanation:
The error you're seeing (SyntaxError: invalid syntax) occurs on line 6 because of the extra colon (:). In Python, the if statement doesn't require a colon after the condition. It's only used for defining a code block within the if statement.
Corrected Code:
Python
print("x y z w") # Print header for output
for x in 0, 1: # Loop through x (0 and 1)
for y in 0, 1: # Loop through y (0 and 1)
for z in 0, 1: # Loop through z (0 and 1)
for w in 0, 1: # Loop through w (0 and 1)
if ((w or (not(x))) and (w == (not(y))) and (w <= z)): # Corrected if statement
print(x, y, z, w) # Print if condition is met
Use code with caution.
Explanation of the Condition:
The condition ((w or (not(x))) and (w == (not(y))) and (w <= z)) checks for specific combinations of x, y, z, and w:
(w or (not(x))): This ensures w is either True or x is False.
(w == (not(y))): This ensures w is the opposite of y (i.e., if y is True, then w must be False, and vice versa).
(w <= z): This guarantees w is less than or equal to z.
Output:
This corrected code will iterate through all possible combinations of x, y, z, and w (16 combinations in total) and print only the ones that satisfy the condition. However, with the given condition, no combinations will meet all three requirements, so the code won't print anything.
