Sum of two variables in RobotFramework

python,automated-tests,robotframework

By default variables are string in Robot. So your first two statements are assigning strings like "xx,yy" to your vars. Then "evaluate" just execute your statement as Python would do. So, adding your two strings with commas will produce a list: $ python >>> 1,2+3,4 (1, 5, 4) So you...

You need to read one bite per iteration, analyze it and then write to another file or to sys.stdout. Try this code: mesh = open("file.mesh", "r") mesh_out = open("file-1.mesh", "w") c = mesh.read(1) if c: mesh_out.write("{") else: exit(0) while True: c = mesh.read(1) if c == "": break if c...

In sklearn, does a fitted pipeline reapply every transform?

python,scikit-learn,pipeline,feature-selection

The pipeline calls transform on the preprocessing and feature selection steps if you call pl.predict. That means that the features selected in training will be selected from the test data (the only thing that makes sense here). It is unclear what you mean by "apply" here. Nothing new will be...

Using counter on array for one value while keeping index of other values

To count how often one value occurs and at the same time you want to select those values, you'd simply select those values and count how many you selected: fruits = [f for f in foods if f[0] == 'fruit'] fruit_count = len(fruits) If you need to do this for...

How does the class_weight parameter in scikit-learn work?

python,scikit-learn

First off, it might not be good to just go by recall alone. You can simply achieve a recall of 100% by classifying everything as the positive class. I usually suggest using AUC for selecting parameters, and then finding a threshold for the operating point (say a given precision level)...
