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)

enumerate python

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

enumerate in python

# Python program to illustrate
# enumerate function in loops

# printing the tuples in object directly
for ele in enumerate(l1):
    print (ele)
>>>(0, 'eat')
>>>(1, 'sleep')

# changing index and printing separately
for count, ele in enumerate(l1, 100):
    print (count, ele)
>>>100 eat
>>>101 sleep
>>>102 repeat  

# getting desired output from tuple
