python - 如何正确加入尾随或破折号开头的单词？ - Python

Question

我有一个字符串列表，其中包含以 - 结尾或开头的标记，我需要将它们连接起来，以便带破折号的单词连接成正确的标记，例如

[输入]:

x = "ko- zo- fond- w- a (* nga- bantawana )."
y = "ngi -leth- el a -unfundi"
z = "ba- ya -gula buye incdai- fv -buye"

[输出]:

kozofondwa (* ngabantawana ).
ngilethel aunfundi
bayagula buye incdaifvbuye

我一直这样做，它真的很丑陋和不雅，尤其是当我需要调用该函数两次时。还有其他方法可以实现相同的输出吗？也许用正则表达式或什么的？

x = "ko- zo- fond- w- a (* nga- bantawana )."
y = "ngi -leth- el a -unfundi"
z = "ba- ya -gula buye incdai- fv -buye"
def join_morph(text):
  tempstr = ""
  outstr = []
  for i in text.split():
    if i.startswith('-'):
      outstr[len(outstr)-1]+=i
    elif i.endswith('-'):
      tempstr+=i
    else:
      tempstr+=i
      outstr.append(tempstr)
      tempstr = ""
  return " ".join(outstr)


# There is a problem because of the ordering of 
# the if-else, it can only handle head or 
# trailing dashes, not both
a = join_morph(x)
print a 
a = join_morph(x).replace('-','')
print a

a = join_morph(join_morph(y)).replace('-','')
print a

a = join_morph(join_morph(z)).replace('-','')
print a

Answer 1

x = "ko- zo- fond- w- a (* nga- bantawana )." #or any other input 
x = x.replace("- ", "").replace(" -", "")

它将从输入中删除所有出现的“-”和“-”，根据需要有效地转换字符串。
