python - Iterating through a string word by word

Question

I wanted to know how to iterate through a string word by word.

string = "this is a string"
for word in string:
    print (word)

The above gives an output:

t
h
i
s

i
s

a

s
t
r
i
n
g

But I am looking for the following output:

this
is
a
string

When you do -

for word in string:

You are not iterating through the words in the string, you are iterating through the characters in the string. To iterate through the words, you would first need to split the string into words , using str.split() , and then iterate through that . Example -

my_string = "this is a string"
for word in my_string.split():
    print (word)

Please note, str.split() , without passing any arguments splits by all whitespaces (space, multiple spaces, tab, newlines, etc).
