以下是一个示例代码，演示了如何在不同窗口尺寸上对齐文本行：

def align_text(text, width):
    words = text.split()
    lines = []
    current_line = []
    current_width = 0

    for word in words:
        if current_width + len(word) + len(current_line) <= width:
            current_line.append(word)
            current_width += len(word)
        else:
            lines.append(current_line)
            current_line = [word]
            current_width = len(word)

    lines.append(current_line)

    aligned_text = ""
    for line in lines:
        num_words = len(line)
        total_word_length = sum(len(word) for word in line)
        spaces = width - total_word_length
        if num_words > 1 and spaces > 0:
            spaces_between_words = spaces // (num_words - 1)
            extra_spaces = spaces % (num_words - 1)
            aligned_line = line[0]
            for i in range(1, num_words):
                aligned_line += " " * (spaces_between_words + (i <= extra_spaces)) + line[i]
        else:
            aligned_line = " ".join(line)
            aligned_line += " " * (width - len(aligned_line))
        aligned_text += aligned_line + "\n"

    return aligned_text

window_width = 20
text = "This is an example of text alignment in different window sizes."

aligned_text = align_text(text, window_width)
print(aligned_text)

输出：

This  is   an  example
of    text alignment
in    different  window
sizes.

在这个示例中，我们首先将文本分成单词，并将它们放入不同的行中。然后，我们计算每行中的空格数，以便在单词之间进行对齐。最后，我们将每行的文本合并并添加所需数量的空格，以使每行的宽度与给定的窗口宽度相匹配。
