Can i calculate exp(1+2j) in python?

exp(1+2j)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: can't convert complex to float

回答1:

You need a complex version of this function:

cmath.exp(1+2j)

See http://docs.python.org/library/cmath.html

回答2:

You may want to import e from the math module to do this.

For example:

>>> from math import e
>>> print e ** (1+2j)
(-1.1312043837568135+2.4717266720048188j)
