Using for loop without accessing sequence items If we don't intend to use items of sequence inside the body of a loop, it is clearer to use the _ (underscore) as the loop variable. For example, # iterate from i = 0 to 3 for _ in range(0, 4: print('Hi') Run Code Output 0...
Baseline: 112.135 ns per loop Improved: 68.304 ns per loop % Improvement: 39.1 % Speedup: 1.64x 3、使用Set 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...
In this tutorial, we’ll cover every facet of theforloop and show you how to use it using various examples. We’ll also go into a few common Python commands and functions likejoin, argv,etc. For more in-depth lessons onforloop and other Python programming concepts, check out this course...
In the second code snippet, we will be using a loop, where we will only have to write whatever tedious task we have to achieve, only once, and then put it on a loop. With this, we will be able to achieve an iterative flow for execution. 在第二个代码段中,我们将使用一个循环,在该...

When you want to iterate over the sequence one way is to iterate using the for loop given below that gives the position of the desired element. The example below iterates over the list of fruits and returns the position of fruit "Mango". ...
foriinrange(len(thistuple)): print(thistuple[i]) Try it Yourself » Using a While Loop You can loop through the tuple items by using awhileloop. Use thelen()function to determine the length of the tuple, then start at 0 and loop your way through the tuple items by referring to th...
