如果程序中倒入pprint模块，就可以使用pprint()和pformat()函数，它们将“漂亮打印”一个字典的字。如果
想要字典中表项的现实比print()的输出结果更干净，这就游泳了。

1、普通打印，示例代码1：
count = {}
message = ‘It was a bright cold day in April, and the clocks were striking thirteen.‘
for character in message:
count.setdefault(character,0)
count[character] = count[character] +1
print(count)
运行结果：
2、漂亮打印，示例代码：
import pprint
count = {}
message = ‘It was a bright cold day in April, and the clocks were striking thirteen.‘
for character in message:
count.setdefault(character,0)
count[character] = count[character] +1
pprint.pprint(count)
运行结果：
3、如果希望得到漂亮打印的文本作为字符串，而不是显示在屏幕上，那就调用pprint.format()，示例代码：
import pprint
count = {}
message = ‘It was a bright cold day in April, and the clocks were striking thirteen.‘
for character in message:
count.setdefault(character,0)
count[character] = count[character] +1
#pprint.pprint(count)
print(pprint.pformat(count))
运行结果：
根据运行结果可以看出，pprint.pprint(count)和print(pprint.pformat(count))是等价的
