Implicit conversion of byte sequences to Unicode text is a thing of the past. This chapter deals with Unicode strings, binary sequences, and the encodings used to convert between them.Depending on your Python programming context, a deeper understanding of Unicode may or may not be of vital ...
complex_num = complex(3, 4)float_num = float(complex_num)代码会抛出异常 TypeError: can't convert complex to float对于复数转化浮点数的运算，其实在Python中，复数提供了2个函数，一个函数是real，返回复数的实数部分，另一个函数是imag，返回复数的虚数部分。a = 4.1+0.3ja.real #输出4.1a.imag...
