print输出格式总结

通过使用ljust(),center(),rjust()函数来实现输入字符串的左右对齐,居中,右对齐等操作;

方法一：(函数不带参数,则默认以空格填充,注意：文字与空格总字符数等于输入的数字)

print("|","Ursula".ljust(20),"|") # 左对齐
print("|","Ursula".center(20),"|") # 居中对齐
print("|","Ursula".rjust(20),"|") # 右对齐

方法二：(函数带参数,则以参数作为填充字符)
print("|","Ursula".ljust(20,"*"),"|") # 左对齐
print("|","Ursula".center(20,"*"),"|") # 居中对齐
print("|","Ursula".rjust(20,"*"),"|") # 右对齐
运行结果：
| **************Ursula |
| *******Ursula******* |
| Ursula************** |
