代码：

#  coding : UTF-8
NAMES=("dog","cat","mouse")
AGES=("3","5","1")
def main(): # 主函数
    with open("d:\\abc.txt", "a") as file:
        for foot in range (len(NAMES)):
            content="{name:<10}{age:>4}\n".format(name=NAMES[foot],age=AGES[foot])
            file.write(content)
if __name__ == "__main__": # 判断程序执行名称
        main() # 调用主函数

代码执行结果：

dog 3
cat 5
