In this tutorial, you'll learn how and when to use the len() Python function. You'll also learn how to customize your class definitions so that objects of a user-defined class can be used as arguments in len().

Notice how the range function will automatically increment the i counter. The loop iterates through all values of i from 0 to 4, which correspond to a range of 5. In python programming, the counting starts from 0, not from 1. The range function generates numbers automatically. Looping over...
The demo loads data in memory using the NumPy loadtxt function: XMLCopy train_x = np.loadtxt(train_file, delimiter="\t", usecols=range(0,13), dtype=np.float32) train_y = np.loadtxt(train_file, delimiter="\t", usecols=[13], dtype=np.float32) test_x = np.loadtxt(test_file...

The Python with statement is a syntactic shortcut to apply a set of common arguments to multiple functions. The demo uses tanh activation on the hidden layer nodes; a common alternative is the sigmoid function. Notice that there’s no activation applied to the output nodes. This is a q...
The outport() function outports the given locals() to the FORTH environment outside the in-line python block. <py> sum = 0 for i in range(100): sum += i print("The sum of 1..100 is ", sum) outport(locals()) </py> It's a block of multiple-line text strings so we ...
for i in range(0, 10): print i This prints the numbers 0 to 9. The value of i is incremented in each iteration. The 'for' command can also be used to iterate over lists and tuples: a5 = ['Aa', 'Bb', 'Cc'] for v in a5: ...
you can take advantage of theOVERclause in aSELECTstatement. This clause lets you define the partitioning and ordering for the rowset and then specify a sliding window (range of rows around the row being evaluated) within which you apply an analytic function, thus computing an aggregated value...
Ran the module through the singlediode.bishop_mpp model (using the newton method) at a range of temperatures from -25 to +74 C in steps of 1 C, and a range of irradiances from 20 to 1100 W/m2 in steps of 20 W/m2. Calculated the efficiency based on the output p_mp and identifi...
