Use Python for the following question.

In a source code file river.py, write a function river(N) that draws a pattern made of N lines with 8 '#' characters.

In this pattern, the first line has all 8 '#' characters starting directly at the left margin.

On the next line, the 8 '#' characters are pushed one space to the right.

Question 2 In a source code file river.py, write a function river (N) that draws a pattern made of N lines with 8 '#' characters. In this pattern, the first line has all 8 '# characters starting directly at the left margin. On the next line, the 8 characters are pushed one space to the right. Every line after this pushes the 8 characters one space further to the right until the 4th line. From line 4 to line 7 the characters are pushed one space closer to the right, and then the alternation starts again until line number N Example Output 1: > river (12) Example Output 2: > river
