列表元祖字典的转换

list1 = [1,2,3,4,5]
list2 = ['python','java','ruby','js','javascript']
dict1 = dict(zip(list1,list2))
print(type(dict1),dict1) #  {1: 'python', 2: 'java', 3: 'ruby', 4: 'js', 5: 'javascript'}


# 2,元祖转成字典：
tup1 = (1,2,3)
tup2 = ('python','java','js')
dict2 = dict(zip(tup1,tup2))
print(type(dict2),dict2) #  {1: 'python', 2: 'java', 3: 'js'}


# 3,列表中嵌套元祖，转成字典：
list3 = [(1,'python'),(2,'java'),(3,'js')]
dict3 = dict(list3)
print(type(dict3),dict3) #  {1: 'python', 2: 'java', 3: 'js'}
