Please help..I believe each line should have an answer of time complexity (big-Oh)..or at least each section if not each line...Please explain as much as possible to help me understand.

1. For each snippet below, give the time complexity (in big-Oh). If it is not possible to say, then explain why. If there is a data structure with variable size, use n to represent the size str . . print (str) for e1 in some list: for e2 in some list: print (1) for i in range(len(10)): for i in range(len (10)) print(i) x [0] * len(some-data-structure) =
