Python dictionariesare a built-indata typefor storingkey-value pairs. The dictionary elements are mutable and don't allow duplicates. Adding a new element appends it to the end, and in Python 3.7+, the elements are ordered. Depending on the desired result and given data, there are various ...
Python data type. It is a sequence of key-value pairs, where each key is unique and maps to a value. Dictionaries are mutable objects, meaning you can change their content without changing their identity. However, dictionary keys are immutable and need to be unique within each dictionary. Th...
Often something physical, such as a Geiger counter or electrostatic noise, where the results are turned into random numbers. We do not need true randomness in machine learning. Instead we can use pseudorandomness. Pseudorandomness is a sample of numbers that look close to random, but were ...
For example, we need to count the number of elements that lies between 30 to 150.Counting values in a certain range in a NumPy arrayNumPy has a counter but it is valid for specific values and not a range of values. Also, if we try the range() function, it will return all the ...

local namespaces -- without this behavior, Python's VM would need to perform at least three name lookups each time a new name is assigned to inside a function (to ensure that the name didn't already exist at module/builtin level), which would significantly slow down a very common ...
