Help me with this code.

Question

#Can anyone explain this code?
import re
pattern =r"spam"

print(list(re.finditer(pattern, "eggspamsausagespam")))

for i in re.finditer(pattern,"eggspamsausagespam"):
print(i.group())
Output
[< re.Match object ; span=(3,7),match='spam'>,re.Match object; span=(14,18),match='spam'>]
spam
spam

Answer 1

1. import re // imports the regular expression module

2. pattern = r"spam" // declares a variable called "pattern" with the row string "spam" as value

3. Now it is better to split the code

- re.finditer(pattern, "eggspamsausagespam") //returns an iterator, which is actually a Match object, if the pattern is matched
- list(...) // puts each matched result in a list
- print(...) //prints the list

4. for in re.finditer(pattern, "eggspamsausagespam") //iterates through each matched result of the iterator
print(i.group()) //prints each group found

I hope you better understand the code now
