python - 如何让 python 的 pprint 返回一个字符串而不是打印？

Question

换句话说，什么是 sprintf 等价于 pprint？

Answer 1

pprint模块有一个名为 pformat 的函数，就是为了这个目的。

来自文档:

Return the formatted representation of object as a string. indent,width and depth will be passed to the PrettyPrinter constructor asformatting parameters.

例子:

>>> import pprint
>>> people = [
...     {"first": "Brian", "last": "Kernighan"}, 
...     {"first": "Dennis", "last": "Richie"},
... ]
>>> pprint.pformat(people, indent=4)
"[   {   'first': 'Brian', 'last': 'Kernighan'},\n    {   'first': 'Dennis', 'last': 'Richie'}]"
