在python中生成替代模式

我已经编写了一个Python脚本来使用嵌套循环生成交替模式。该模式遵循奇数和偶数索引,并且我包含了一个条件,以避免列索引为零时出现负值。

n = 5

for i in range(n):
    for j in range(i+1):
        if i % 2 == 0 and j % 2 == 0: # Check if both row and column indices are even for alternating sets
            print(f"{i*10} {j*10}")
            if j != 0: # avoid negative in 0.
            
                print(f"{i*10} -{j*10}")  
        if i % 2 != 0 and j % 2 != 0: # Check if both row and column indices are odd for alternating sets.
        
            print(f"{i*10} {j*10}")
            print(f"{i*10} -{j*10}")

它会产生你的欲望模式

0 0
10 10
10 -10
20 0
20 20
20 -20
30 10
30 -10
30 30
30 -30
40 0
40 20
40 -20
40 40
40 -40

使用逐位AND(&)并调整生成交替模式的条件的另一个或替代解决方案。

n = 5
for i in range(n):
    if i % 2 != 0:
        for j in range(1, i + 1):
            if i != j & i % 2 != 0:
                print(i * 10, j * 10)
                print(i * 10, -j * 10)
    elif i % 2 == 0:
        for j in range(i + 1):
            if j * 20 <= i * 10:
                print(i * 10, j * 20)
                if j != 0:
                    print(i * 10, -j * 20)

def generate_alternative_pattern():
    # Initial values
    x, y = 0, 0
    step = 10

    # Print the first two sets of values
    print(x, y)
    print(x + step, y + step)

    # Generate the alternative pattern
    for _ in range(5):
