字符串格式化操作符(%)只适用于字符串类型，非常类似于C 语言里面的printf()函数的字符串格式化，甚至所用的符号都一样，都用百分号(%)，并且支持所有printf()式的格式化操作。语法如下：
format_string % string_to_convert
format_string为格式标记字符串，形式为“%cdoe”；string_to_convert 为要格式化的字符串，如果是两个以上，则需要用小括号括起来。

字符串格式化输出举例：
charA = 65
charB = 66
print("ASCII码65代表：%c" % charA)
print("ASCII码66代表：%c" % charB)
Num1 = 0xEF3
Num2 = 0xAB03
print('转换成十进制分别为：%u和%u' % (Num1, Num2))
Num3 = 1200000
print('转换成科学计数法为：%e' % Num3)
输出：
ASCII码65代表：A
ASCII码66代表：B
转换成十进制分别为：3827和43779
转换成科学计数法为：1.200000e+06
当然，还有一些辅助符号，如下表所示：

辅助符号举例：
Num1 = 108
print("%#X" % Num1)
Num2 = 234.567890
print("%.2f" % Num2)
输出：
