Question

我有一個字符串數組。 我想打印以 New 開頭的那些。

input_arr = [
    "New: Hello",
    "How are",
    "you",
    "New: I am",
    "fine"
]

def merge_messages(input_arr):
      #don't know that to do here
  return input_arr

print(merge_messages(input_arr))

#Expected Output
[
"New: Hello How are you",
"New: I am fine"
]

Answer 1

input_arr = [
    "New: Hello",
    "How are",
    "you",
    "New: I am",
    "fine"
]

def merge_messages(input_arr):
  delimiter = "New"
  return [delimiter+x for x in " ".join(input_arr).split(delimiter) if x]

print(merge_messages(input_arr))
