Python | Get the first key in dictionary Many times, while working with Python, we can have a situation in which we require to get the initial key of the dictionary. This method returns a list of all the available keys in the dictionary. Example.

NA。 返回值. 以下实例展示了 keys()函数的使用方法： #!/usr/bin/python dict = {'Name': 'Zara', 'Age': 7} print "Value : %s" % dict.keys() Python dictionary method keys () returns a list of all the available keys in the dictionary. Parameters. Dictionary provides a method get () that accepts a key and default value. items (), in dictionary iterates over all the keys and helps us to access the key-value pair one after the another in the loop and is also a good method to access dictionary keys with value. There can be many specific uses of it, either for checking the indexing and many more of these kinds.

Python dictionary keys () Method Description. Python Dict Wrapper. dict.keys () returns an iterable of type dict_keys (). The view object contains the keys of the dictionary, as a list. dict.get (key [, default]) 1. dict.get(key[, default]) If given key exists in dictionary then it returns its value, If given key does not exists in dictionary then it returns the passed default value argument. The keys()method returns a view object. Syntax. keys()方法语法： dict.keys() 参数. Also, you can use * operator, which unpacks an iterable. You can get all the keys in the dictionary as a Python List.
