1.字典(dict) 2.元组(tuple) 3.文件 4.数据类型总结 这节课我们学习Python中其他的数据类型,首先字典表(dict)它是通过键-值对的形式存储数据的一种格式,在其他的编程语言中也被称为hash表,在字典表中元素没有下标也没有先后顺序,仅依靠它的键值对应。之后学习了元组(tuple),它是不可原位改变的数据类型。最...
python dict remove,删除 我们在用列表做删除的时候,可能选择2个方法,一个是del,一个是pop方法。 比如代码 binfo = {'name':'jay','age':20,'python':'haha'} print binfo.pop('name')#pop方法删除键,并且返回键对应的值 print binfo##输出结果:{'python': 'haha', 'age': 20} del binfo['py...

If dict, value at 'method' is the compression mode. Compression mode may be any of the following possible values: {'infer', 'gzip', 'bz2', 'zip', 'xz', None}. If compression mode is 'infer' and `path_or_buf` is path-like, then detect compression mode from the following ...
