python iterate over 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: how to iterate over a list in python

# Python list
my_list = [1, 2, 3]

# Python automatically create an item for you in the for loop
for item in my_list:
  print(item)

Example 5: how to loop through list in python

thisList = [1, 2, 3, 4, 5, 6]

x = 0
while(x < len(thisList)):
    print(thisList[x])
    x += 1
    
# or you can do this:

for x in range(0, len(thisList)):
    print(thisList[x])
    
#or you can do this

for x in thisList:
    print(x)

Example 6: how to loop through a list

List<int> list = new List<int> { 1, 2, 3, 4, 5 };
//For Loop
for (int i = 0; i < list.Count(); i++)
{ Console.WriteLine(list[i]); }

//For Each Loop
foreach (int item in list)
{ Console.WriteLine(item); }
