Python standard library: Built-in function dict (mapping, **kwarg)

This function constructs a new dictionary from a mapped function object.

Unlike the dict (**kwarg) function, a parameter input is a function object of a mapping type, such as a zip function,amap function.

Examples:

#dict () #以键对方式构造字典d1 = dict (one = 1, one = 2, a = 3) print (D1) #以映射函数方式来构造字典d2 = Dict ([' One ', ' one ', ' B ', ' Three '], [1, 2, 3]) ) Print (D2)

The output results are as follows:

{' A ': 3, ' one ': 1, ' both ': 2}

{' Three ': 3, ' one ': 2, ' One ': 1}
