How to Extract words from list in Python-CodePudding

I have a string str1 with the following format, and I need to extract all the words starting with "SF-", without duplication.

I tried this:

newlist=[]
# Driver code
str1 = '"SF-9632":"schema,names","startAt":0,"maxResults":50,"total":58,"issues","SF-6349","total":70,"SF-6533'
for x in str1:
    if "SF-" in str1:
        newlist.append(x)

print(newlist)

The output inside newlist is equal to str1.

You missed the split operation which breaks your main string str1 into an array:

newlist=[]
# Driver code
str1 = '"SF-9632":"schema,names","startAt":0,"maxResults":50,"total":58,"issues","SF-6349","total":70,"SF-6533'
lstr1 = str1.split("\"")
for x in lstr1:
    if "SF-" in x:
        newlist.append(x)

newlist = list(set(newlist))
print(newlist)

Which then outputs:

['SF-9632', 'SF-6349', 'SF-6533']

Thank you that is what I needed.
