python如何用函数创造字典

dict1 = dict(a='a', b='b', t='t')     # 传入关键字

print(dict1)

dict2 = dict(zip(['one', 'two', 'three'], [1, 2, 3]))   # 映射函数方式来构造字典

print(dict2)

dict3 = dict([('one', 1), ('two', 2), ('three', 3)])    # 可迭代对象方式来构造字典

print(dict3)

dict3 = dict.fromkeys(['name','age'])

print(dict3)

dict4 = dict.fromkeys(['name','age'],10)

print(dict4)
