7) 按顺序遍历 (Looping in sorted order) #我们希望输出的元素是按照水果名字的字典顺序 #也就是让以a开头的排在最前面 ,以 z开头的排在最后面 # 使用python中的内建函数sorted() for i,x in enumerate(sorted(fruit)): print(i,x) 1. 2. 3. 4. 5. 6. 7. 8. 9. 8)字典合并操作 (Dictionar...
Using thepop()andinsert()functions in Python is a straightforward approach to swapping elements within a list. Thepop()function is employed to remove elements from specific indices, and theinsert()function is then used to insert those elements back into the desired positions. ...
In this next example, we will use Python’szip() functionto swap the arrangement of the 2D list: transposed=list(zip(*original))print(transposed)# [(1, 3, 5), (2, 4, 6)] Thezip()function takes any number of iterables as arguments and returns an iterator that aggregates elements ...
