optional conditions, and an expression. A for loop goes through the sequence. For each loop an expression is evaluated if the condition is met. If the value is computed it is appended to the new list. There can be multiple for loops and if conditions. ...

In the following example, we have two loops. The outerforloop iterates the first four numbers using therange()function, and the innerforloop also iterates the first four numbers. If theouter number and a current number of the inner loopare the same, then break the inner (nested) loop. ...
We have a two-dimensional list of integers. We loop over the elements with twoforloops. $ ./loop_nested.py 1 2 3 4 5 6 7 8 9 Python list loop with zip Thezipfunction creates an iterator from the given iterables. for_loop_zip.py #!/usr/bin/python words1 = ["cup", "bottle",...
This example shows how to create a list of coordinate pairs using nested loops in a list comprehension. Code: # Create a list of coordinate pairs (x, y) for x and y in range(3) pairs = [(x, y) for x in range(3) for y in range(3)] ...
How to implement nested for loops in Python? You can implement nested for loops using various techniques of Python. Python provides two types of loops
More on Python List Comprehension Nested List Comprehension We can also use nested loops in list comprehension. Let's write code to compute a multiplication table. multiplication = [[i * j for j in range(1, 6)] for i in range(2, 5)] print(multiplication) Run Code Output [[2, 4...
Using a for loops in Python we can automate and repeat tasks in an efficient manner. So the bottom line is using the for loop we can repeat the block of statements a fixed number of times. Let’s understand this with an example. As opposed to while loops that execute until a condition...
Learn Python list comprehension with easy examples. Discover how to create lists efficiently using concise, readable syntax for loops, conditions, and more.
print(newlist) 1 ['red cat', 'red dog', 'red bird', 'green cat', 'green dog', 'green bird', 'blue cat', 'blue dog', 'blue bird'] can be done as follows, with two “for” inside the list comprehension: 1 2 3 4 5 colors = ["red", "green", "blue"] animals = [...
