loop in pyhton code example

Example 1: python loops

#x starts at 1 and goes up to 80 @ intervals of 2
for x in range(1, 80, 2):
  print(x)

Example 2: 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 3: loops in python

#While Loop:
while ("condition that if true the loop continues"):
  #Do whatever you want here
else: #If the while loop reaches the end do the things inside here
  #Do whatever you want here

#For Loop:
for x in range("how many times you want to run"):
  #Do whatever you want here

Example 4: for in python

for i in range(1,10,2): #(initial,final but not included,gap)
  print(i); 
  #output: 1,3,5,7,9
  
for i in range (1,4): # (initial, final but not included)
  print(i);
  #output: 1,2,3 note: 4 not included

for i in range (5):
  print (i);
  #output: 0,1,2,3,4 note: 5 not included

python = ["ml","ai","dl"];  
for i in python:
  print(i);
  #output:  ml,ai,dl
  
for i in range(1,5):	#empty loop...if pass not used then it will return error
  pass;

Example 5: python for loop

#an object to iterate over 
items = ["Item1", "Item2", "Item3", "Item4"]

#for loop using range  
for i in range(len(items)):
  	print(items[i])
    
#for loop w/o using range    
for item in items:
  	print(item)

Example 6: 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
