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.

python for loop

# Range:
for x in range(5):
  print(x) # prints 0,1,2,3,4

# Lists:
letters = ['a', 'b', 'c']
for letter in letters:
  print(letter) # prints a, b, c
  
# Dictionaries:
letters = {'a': 1, 'b': 2, 'c': 3}
for letter, num in letters.items():
  print(letter, num) # prints a 1, b 2, c 3

how to make a loop in python
