Implement the Dijkstra's Algorithm in PYTHON. Show the complete source code (text format) and screenshot/s of the running output.

Please write a program using python to show the movement of polymerase in transcription elongation model. For example, there are some nucleotides, 'ATCCTGCAAGTC...'. If polymerase chooses the correct complementary nucleotides, it moves forward. if it chooses a wrong nuceotide, it moves backward.

Find an example of a Python program on the Web that illustrates the program’s decisions using if and while statements. Provide a link for the source. What is happening in your programming example? Describe it in English as an algorithm. After the else statement executes, which program statement executes next in your example?

I need help fixing the python code so that it can output the image given in the image displayed below : rows = int(input()) k = 2 * rows - 2 for i in range(rows,0):        for j in range(k, 0):        print("*", end=" ")    k = k - 2    for j in range(i+1, 0):        print(end="")    print("")
