Stuck, again
trouble with result, i have to much spaces My result: "left, left, left, stop" And correct result "left,left,left,stop" but if remove them, next assert will be failed
My Code:
def left_join(phrases): """ Join strings and replace "right" to "left" """ import re phrase=str(phrases) phrase=re.sub('[\'()]','',phrase) return phrase.replace('right','left') if __name__ == '__main__': #These "asserts" using only for self-checking and not necessary for auto-testing assert left_join(("left", "right", "left", "stop")) == "left,left,left,stop", "All to left" assert left_join(("bright aright", "ok")) == "bleft aleft,ok", "Bright Left" assert left_join(("brightness wright",)) == "bleftness wleft", "One phrase" assert left_join(("enough", "jokes")) == "enough,jokes", "Nothing to replace"
