python loop in list code example

Example 1: python loop through list

list = [1, 3, 6, 9, 12] 
   
for i in list: 
    print(i)

Example 2: how to loop over list

# Python code to iterate over a list
list = [1, 2, 3, 4, 5, 6]

# Method 1: Using "var_name in list" syntax
# Pro: Consise, easily readable
# Con: Can't access index of item
for item in list:
  print(item)
  
# Method 2: Using list indices
# Pro: Can access index of item in list
# Con: Less consise, more complicated to read
for index in range(len(list)-1):
  print(list[index])
  
# Method 3: Using enumerate()
# Pro: Can easily access index of item in list
# Con: May be too verbose for some coders
for index, value in enumerate(list):
  print(value)

Example 3: list loop python

list = [1, 3, 5, 7, 9] 

# with index   
for index, item in enumerate(list): 
    print (item, " at index ", index)
    
# without index
for item in list:
  	print(item)

Example 4: python iterate list

for var_name in input_list_name:
