The value taken from range() at each step is stored in the variable _, which you use here because you don’t actually need this value inside of the loop.At each step of the loop, random.uniform() generates a new random number between -0.05 and 0.05, which you assign to the variable...
pandas dataframe loop 1. Use vectorized operations: Instead of using for loops, try to use vectorized operations like apply, map, or applymap, which can significantly improve the efficiency of your code. 2. Use iterrows() and itertuples() sparingly: These methods iterate over the rows of th...
