2.1 Get Length of 2-D Array in Python You can also use the Python len() function to compute the length of a 2-D array. Before going to calculate the length of the 2-D array we need to find the number of rows and columns. The length of the 2-D array is the multiplication of a...
You can use the built-ineval()to evaluate arbitrary Python expressions from string-based or compiled-code-based input. This is a good option if you need to dynamically evaluate Python expressions. When you pass a string argument toeval(), it compiles it into bytecode and evaluates it as a...
