I was playing with index and did finding letter's place

sentence = "Coding is hard"

index = sentence.index("i")
print(index)

worked fine for me, however when I wanted to find more than just 1 i it didn't work?

sentence = "Coding is hard"

index = sentence.index("i", index   1) 
print(index)

it doesn't work? can somebody explain please?

CodePudding user response：

While index() is one approach, and commenters have given you pointers to help with that, another way to find all occurrences of a character in a string is to use a list comprehension:

sentence = "Coding is hard"
indices = [i for i, c in enumerate(sentence) if c == "i"]
print(indices)

This prints:

[3, 7]
