使文本行具有相同的长度

lines = ["Hello", "World", "Python"]
max_length = max(len(line) for line in lines)

for i in range(len(lines)):
    lines[i] = lines[i].ljust(max_length)

lines = ["Hello", "World", "Python"]
max_length = max(len(line) for line in lines)

for i in range(len(lines)):
    lines[i] = format(lines[i], f"<{max_length}}")

lines = ["Hello", "World", "Python"]
max_length = max(len(line) for line in lines)

for i in range(len(lines)):
    lines[i] = f"{lines[i]:<{max_length}}"

['Hello     ', 'World     ', 'Python    ']
