Look up in the list

There are no more than the following operations to find a list:

Traverse the list

Find the element of the specified index

Find the element of the specified value

Lists can be traversed in three ways: index traversal, value traversal, and enumerate () traversal.

List1 = ["Python", "C++", "Java"] # method 1for i in range (len (list1)): print (List1 [I]) # method 2, the traversal speed is the most efficient, but the index cannot be recorded for i in list1: print (I) # method 3for index, val in enumerate (list1): print (val)

There are two kinds of lookup elements, one is to look up by index, and the other is to traverse to find by value.

# find the elements of the specified index list1 = [1, 3, 2, 5, 7, 8] list1 [3] # returns the element with an index of 3, and the value key = 5for I in list1: if I = = key: print ("OK") # find the maximum and minimum elements max (list1) # 8min (list1) # 1 and above are all the contents of the article "how python implements the search operation in the list" Thank you for reading!
