enumerate in python 3 code example

Example 1: enumerate in python

languages = ['Python', 'C', 'C++', 'C#', 'Java']

#Bad way
i = 0 #counter variable
for language in languages:
    print(i, language)
    i+=1

#Good Way
for i, language in enumerate(languages):
    print(i, language)

Example 2: enumerate python

for index,subj in enumerate(subjects):
    print(index,subj) ## enumerate will fetch the index
    
0 Statistics
1 Artificial intelligence
2 Biology
3 Commerce
4 Science

5-->f

Example 4: how to use enumerate in python

rhymes=['check','make','rake']
for rhyme in enumerate(rhymes):
    print(rhyme)
#prints out :
(0, 'check')
(1, 'make')
(2, 'rake')
#basically just prints out list elements with their index

Example 5: enumerate in python

list1 = ['1', '2', '3', '4']

for index, listElement in enumerate(list1): 
    #What enumerate does is, it gives you the index as well as the element in an iterable
    print(f'{listElement} is at index {index}') # This print statement is just for example output

# This code will give output : 
"""
1 is at index 0
2 is at index 1
3 is at index 2
4 is at index 3
"""

Example 6: enumerate python

grocery = ['bread', 'milk', 'butter']

for item in enumerate(grocery):
  print(item)

print('\n')
for count, item in enumerate(grocery):
  print(count, item)

print('\n')
# changing default start value
for count, item in enumerate(grocery, 100):
  print(count, item)
  
OUTPUT: 
(0, 'bread')
(1, 'milk')
(2, 'butter')

0 bread
1 milk
2 butter

100 bread
101 milk
102 butter
