python - Issue in conplex

Question

I write this simple code,but I catch multiple errors.

v0[t]=abs(values_list[k]-list(x1)) TypeError: unsupported operand type(s) for -: 'complex' and 'list'

I appreciate any help.

x1=[1.5+1.2j]
import numpy as np
import matplotlib.pyplot as plt
import math
mapping = {
          (0,0,0,0) : -3-3j,
          (0,0,0,1) : -3-1j,
          }  
modulation=4
values= mapping.values()# extract values
values_list = list(values)# tuple to list
print(values_list[0])
v0=[0,0]
t=0
for k in  range(2):
 v0[t]=abs(values_list[k]-list(x1)) 
 print(k)

Answer 1

TypeError: unsupported operand type(s) for -: 'complex' and 'list'

This mean you tried to subtract list from complex number, you are doing:

x1=[1.5+1.2j]

...

v0[t]=abs(values_list[k]-list(x1))

I suppose x1 should be complex. Then change first to x1=1.5+1.2j (currently this is list with one complex) and second to v0[t]=abs(values_list[k]-x1).
