I Keep getting this error, It's so simple and error is about (-x) in function but I don't know how I can fix it. Please help me.
This is my code:
import numpy as np x = list(np.arange(0, 1, 0.1)) print (x) def f(x): f = np.exp(-x) return f y =f(x) print (y) 2 Answers
Broadcasting isn't supported for vanilla Python lists. You should use list() after the operation involving broadcasting, like so:
import numpy as np x = np.arange(0, 1, 0.1) print(x) def f(x): f = np.exp(-x) return f y = list(f(x)) print(y) First of all, please use different names
import numpy as np x = list(np.arange(0, 1, 0.1)) print (x) def func(param): retval = np.exp(-param) return retval y = func(x) print (y) for start.
Then, you make a list from the np.arange, python lists don't support the unary operation - (minus) as you are using in the function (i.e. f = np.exp(-x))
numpy arrays on the other hand do support it. what you can do is not convert it to python list, or only convert it to a python list later in the process (after using the minus)
