Python - Strings

optimized join chars,words,sentences.py

# Remember str are immutable objects
# IMPORTANT: only worth it for really long strings!
# otherwise just use += 

# Summary: Append them to a list, join them with "".join()

charlist = []
text = ''
# it would also work for words, sentences, ...
for char in text_to_loop:
    charlist.append(char)
# we construct the string with the optimized str.join() method:
text = "".join(charlist)
