For each line of code: 1. Explain what it does in detail. 2. Write down the output that is generated by it. x = "This is a string." print(x[1:7:2]) print(x[1:2:7]) print(x[1:2]) print("") print(x[2:-1]) print(x[2:-1:1]) print(x[2:-1:2]) print("") print(x[::-1]) print(x[::2]) print(x[::3]) print(x[::-2]) print("") print(x[0:-2:2]) print(x[:-2:2]) print(x[:1:-1]) print(x[:1:-2]) print(x[:-6:-2]) print("") print(x[0:len(x)]) print(x[0:len(x) - 1]) x = x[0:-1] print(x)
