Replace multiple occurrences in string

Question

I want to replace all occurrences of double quotes with single quotes. But only in the img tag! I have a html text

<p>First p</p><img class="image" src="one.jpg" />
<p>Second p</p><img class="image" src="two.jpg" />

How can I replace this "in place". I tried something like this:

re.sub('"', "'", re.findall(r'<img.*/>', html))

The expected result is this:

<p>First p</p><img class='image' src='one.jpg' />
<p>Second p</p><img class='image' src='two.jpg' />

Assuming that the html tags are a `str` type, you can use s.replace("\"", "\'")) — Manjunath, Dec 04 '17 at 12:46

re.findall() returns a list, while re.sub() expects a string as the input

r=re.findall(r'<img.*>', html)
b=[re.sub('"', "'",a) for a in r]
for i in range(len(b)):
    html=str.replace(html,r[i],b[i])
print html

Output

<p>First p</p><img class='image' src='one.jpg' />
<p>Second p</p><img class='image' src='two.jpg' />
