In each iteration of the loop, the variableiget the current value. Example: Print first 10 numbers using a for loop Here we used the range() function to generate integers from 0 to 9 Next, we used theforloop to iterate over the numbers produced by therange()function ...
The continue statement skips the current iteration of the loop and continues with the next iteration. For example, languages = ['Swift', 'Python', 'Go', 'C++'] for lang in languages: if lang == 'Go': continue print(lang) Run Code Output Swift Python C++ Here, when lang is equal ...
在使用for循环进行比较的情况下使用set。 # Use for loops for nested lookups def test_03_v0(list_1, list_2): # Baseline version (Inefficient way) # (nested lookups using for loop) common_items = [] for item in list_1: if item in list_2: common_items.append(item) return common_item...
