iterate python code example

Example 1: loop through python object

for attr, value in k.__dict__.items():
        print(attr, value)

Example 2: python return iteration number of for loop

# Basic syntax:
for iteration, item in enumerate(iteratable_object):
	print(iteration)
# Where:
#	- item is the current element in the iteratable_object
#	- iteration is the iteration number/count for the current iteration

# Basic syntax using list comprehension:
[iteration for iteration, item in enumerate(iteratable_object)]

# Example usage:
your_list = ["a", "b", "c", "d"]

for iteration,item in enumerate(your_list):
	(iteration, item) # Return tuples of iteration, item
--> (0, 'a')
	(1, 'b')
	(2, 'c')
	(3, 'd')

[iteration for iteration, item in enumerate(your_list)]
--> [0, 1, 2, 3]

Example 3: what is iteration in python

# Iteration is the execution of a statement repeatedly and without
# making any errors.

Example 4: how to use iteration in python

>>> a = ['foo', 'bar', 'baz']
>>> for i in a:
...     print(i)
...
foo
bar
baz

Example 5: enumerate dictionary python

# Iterate over dictionary using enumerate()

mydict = {
	"one": 1,
  	"two": 2,
  	"three": 3
}

# You can replace `index` with an underscore to ignore the index 
# value if you don't plan to use it.
for index, item in enumerate(mydict):
	print(f"{item}: {mydict.get(item)}")

# OUTPUT:
# one: 1
# two: 2
# three: 3

Example 6: how to use iteration in python

for i = 1 to 10
    <loop body>
