Nested For Loops Nested loops are nothing but loops inside a loop. You can create any number of loops inside a loop. Roughly a nested loop structure looks similar to this: for[first iterating variable]in[outer loop]:# Outer loop[do something]# Optionalfor[second iterating variable]in[neste...

Since the output will be a nested list, you would first flatten the list and then pass it to the DataFrame. Finally, save the dataframe as a CSV file. results = [] for i in range(1, no_pages+1): results.append(get_data(i)) flatten = lambda l: [item for sublist in l for ite...
