my_number =complex(input("Number")) Note that Python uses "j" as a symbol for the imaginary component; you will have to tell your user to input numbers in this format:1+3j If you would like your calculator to support a different syntax, you will have to parse the input and feed it...
复数(Complex)是Python的内置类型,直接书写即可。换句话说,Python 语言本身就支持复数,而不依赖于标准库或者第三方库。 复数由实部(real)和虚部(imag)构成,在 Python 中,复数的虚部以j或者J作为后缀,具体格式为: a + bj a 表示实部,b 表示虚部。
it will be interpreted as a complex number and the function must be called without a second parameter. The second parameter can never be a string. Each argument may be any numeric type (including complex). Ifimagis omitted, it defaults to zero and the constructor serves as a numeric conversi...
