25, there are the following variables, please implement the required functions
Tu= ("Alex", [11,22,{"K1": ' V1 ', "K2": ["Age", "name"], "K3":(11,22,33)},44])
A. Characteristics of Ganso: tuples have all the attributes of a list, but the elements of a tuple cannot be modified

B. Can you tell me if the first element in the TU variable, "Alex", could be modified? : Cannot be modified.

C. What is the value of "K2" in the TU variable? Is it possible to be modified? If you can, add an element, "Seven", to the

List, you can modify

Tu= ("Alex", [11,22,{"K1": ' V1 ', "K2": ["Age", "name"], "K3":(11,22,33)},44])
tu[1][2][' K2 '].append (' Seven ')
Print (TU)
D. What is the value of "K3" in the TU variable? Is it possible to be modified? If you can, add an element, "Seven", to the
Tuples, cannot be modified

26. Dictionaries
dic={' K1 ': "v1", "K2": "V2", "K3": [11,22,33]}
A. Please loop out all the keys:

dic={' K1 ': "v1", "K2": "V2", "K3": [11,22,33]}
For I in Dic.keys ():
    Print (i)

B. Please loop out all the value

dic={' K1 ': "v1", "K2": "V2", "K3": [11,22,33]}
For I in Dic.values ():
    Print (i)
C. Please loop out all the keys and value

dic={' K1 ': "v1", "K2": "V2", "K3": [11,22,33]}
For i,v in Dic.items ():
    Print (I,V)
D. Add a key-value pair in the dictionary, "K4": "V4", and output the added dictionary

dic={' K1 ': "v1", "K2": "V2", "K3": [11,22,33]}
dic[' K4 ']= ' v4 '
Print (DIC)
E. In the modified dictionary, the value of "K1" corresponds to "Alex", Output the modified dictionary

dic={' K1 ': "v1", "K2": "V2", "K3": [11,22,33]}
dic[' K1 ']= ' Alex '
Print (DIC)
F. Please append an element 44 to the value of the K3, and output the modified dictionary

dic={' K1 ': "v1", "K2": "V2", "K3": [11,22,33]}
dic[' K3 '].append (44)
Print (DIC)
G. Insert element 18 in the 1th position of the K3 corresponding value, output the modified dictionary

dic={' K1 ': "v1", "K2": "V2", "K3": [11,22,33]}
dic[' K3 '].insert (0,18)
Print (DIC)

27. Conversion
A. Converting a string s= "Alex" to a list

S= "Alex"
Li=list (s)
Print (LI)
B. Convert the string s= "Alex" to Cheng Yuanju

S= "Alex"
Li=tuple (s)
Print (LI)
B. Convert the list li=["Alex", "seven"] to Narimoto Group

li=["Alex", "seven"]
Tu=tuple (LI)
Print (TU)
C. Convert the tu= (' Alex ', ' seven ') to a list

tu= (' Alex ', ' seven ')
Li=list (TU)
Print (LI)
D. Convert the list li=["Alex", "seven"] to a dictionary and the dictionary key is incremented backwards by 10
