python3 for loop code example

Example 1: python for loop

# A for loop in python is used to iterate (or loop) over a sequence.
# The sequence is usually range(start,end), but can also be a list.
# Example of for loop with range():
for num in range(1,10):
  print(num)
  # This prints all the numbers from 1 to 10, including 1 but excluding 10.

 # Here is an example of a for loop with a list:
lst = [1,2,3,4,5]
for item in lst:
  print(item)
  # This prints all items in the list.

# For loops are also used in list comprehensions.
lst = [1,2,3,4,5]
new_lst = [item for item in lst if i % 2 == 0]
# The list comprehension above generates a new list, which new_lst is put equal to.
# It iterates through the items in lst and only puts them in the new list if it is a multiple of 2.

Example 2: how to use a for loop in python

a_list = [1,2,3,4,5]

#this loops through each element in the list and sets it equal to x
for x in a_list:
	print(x)

Example 3: for in python

# how to use for in python for (range, lists)
fruits = ["pineapple","apple", "banana", "cherry"]
for x in fruits:
  if x == "apple":
    continue
  if x == "banana":
    break
  print(x)
# fron 2 to 30 by 3 step
for x in range(2, 30, 3):
  print(x)

Example 4: python for loop

for x in range(10):
	print(x)
// output: 1,2,3,...,10
    
for x in range(10, 20, 2):
	print(x)
// output: 10, 12, 14, 16, 18, 20

list = [2, 3, "el"]
for x in list:
	print(x)
// output: 2, 3, "el"

for _ in range(10):
  print("a");
// Do the loop without using index

Example 5: for each loop python 3

# 'foreach' in python is done using 'for'
for val in array:
    print(val)

Example 6: for loop example python 3

for num in nums:
     for letter in 'abs':
         print(num, letter)
