How do you do natural logs (e.g. "ln()") with numpy in Python?Correct, np.log(x) is the Natural Log (base e log) of x. For other bases, remember this law of logs: log-b(x) = log-k(x) / log-k(b) where log-b is the log in some arbitrary base b, and log-k is the log in base k, e.g. here k = e. l = np.log(x) / np.log(100) and l is the log-base-100 of x

5 Best Ways to Compute the Natural Logarithm in PythonMethod 1: Using math.log. The math module in Python provides a convenient method called log, which can be used to compute the natural logarithm of a number. The log function can take one argument, representing the number you wish to find the logarithm for, and returns the natural logarithm of that number if no base is specified. Here ...
