L = range(1,10) for x in L: print(x*x)
L = range(1,10) L2 = [] for x in L: L2.append( x*x ) print(L2)
L2 = [x*x for x in range(1,10)] print(L2)
L2 = [x*x for x in range(1,10)]
L2 = [] for x in range(1,10): L2.append( x*x ) print(L2)
1. Construct a new list
2. The list source is an iteration
3. Each new element is calculated from the source element.
4. Result list
scores = [34, 65, 45, 67, 78, 56, 80]passed_scores = [x for x in scores if x >= 60]print(passed_scores) # Result:# [65, 67, 78, 80]
scores = [34, 65, 45, 67, 78, 56, 80]L = [x for x in scores if x >= 60]
L = [] for x in scores: if x >= 60: L.append(x)
4. Each new element is calculated from the source element.
5. Result list
3. Add to the list according to condition
scores = [34, 65, 45, 67, 78, 56, 80] L = [x for x in scores if x >= 60]
