将字典键和值拆分为单独的列表

给定字典，任务是将该字典拆分为键，并将值拆分为不同的列表。让我们讨论执行此操作的不同方法。

方法1：使用 built-in functions

# Python code to demonstrate
# to split dictionary
# into keys and values

# initialising _dictionary
ini_dict = {'a': 'akshat', 'b': 'bhuvan', 'c': 'chandan'}

# printing iniial_dictionary
print("intial_dictionary", str(ini_dict))

# split dictionary into keys and values
keys = ini_dict.keys()
values = ini_dict.values()

# printing keys and values separately
print("keys : ", str(keys))
print("values : ", str(values))

输出：

intial_dictionary {'a'：'akshat'，'b'：'bhuvan'，'c'：'chandan'}
键：dict_keys（['a'，'b'，'c']）
值：dict_values（['akshat'，'bhuvan'，'chandan']）

 
方法2：使用 zip()

# Python code to demonstrate
# to split dictionary
# into keys and values

# initialising _dictionary
ini_dict = {'a': 'akshat', 'b': 'bhuvan', 'c': 'chandan'}

# printing iniial_dictionary
print("intial_dictionary", str(ini_dict))

# split dictionary into keys and values
keys, values = zip(*ini_dict.items())

# printing keys and values separately
print("keys : ", str(keys))
print("values : ", str(values))

输出：

intial_dictionary {'a'：'akshat'，'c'：'chandan'，'b'：'bhuvan'}
键：（'a'，'c'，'b'）
值：（“ akshat”，“ chandan”，“ bhuvan”）

 
方法＃3：使用 items()

# Python code to demonstrate
# to split dictionary
# into keys and values

# initialising _dictionary
ini_dict = {'a' : 'akshat', 'b' : 'bhuvan', 'c': 'chandan'}

# printing iniial_dictionary
print("intial_dictionary", str(ini_dict))

# split dictionary into keys and values
keys = []
values = []
items = ini_dict.items()
for item in items:
    keys.append(item[0]), values.append(item[1])

# printing keys and values separately
print ("keys : ", str(keys))
print ("values : ", str(values))

输出：

intial_dictionary {'b'：'bhuvan'，'c'：'chandan'，'a'：'akshat'}
键：['b'，'c'，'a']
值：['bhuvan'，'chandan'，'akshat']
