Nested loops in MicroPython on Raspberry Pi Pico refer to the use of one loop inside another loop. The inner loop is executed multiple times for each iteration of the outer loop. This technique is useful when we want to perform repetitive tasks or calculations on a set of data.
To create nested loops in MicroPython on Raspberry Pi Pico, we simply need to place one loop inside another loop. Here’s an example:
for i in range(3):
for j in range(2):
print(i, j)In this example, we have an outer loop that iterates from 0 to 2, and an inner loop that iterates from 0 to 1. For each iteration of the outer loop, the inner loop is executed twice. The output of this code would be:
0 0
0 1
1 0
1 1
2 0
2 1We can also use nested loops to access and modify elements of a two-dimensional list or array. Here’s an example:
matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
for row in matrix:
for element in row:
print(element)In this example, we have a two-dimensional list called matrix. The outer loop iterates over each row of the matrix, while the inner loop iterates over each element in the current row. The output of this code would be:
1
2
3
4
5
6
7
8
