除非在引号之间找到空格，否则使用空格作为分隔符在python中拆分字符串[重复]答案

【问题标题】：splting a string in python using space as delimiter unless the space is found between quotation marks [duplicate]除非在引号之间找到空格，否则使用空格作为分隔符在python中拆分字符串[重复]

【问题描述】：

我想使用空格作为分隔符来分割文本，除非在引号之间找到空格

例如

string = "my name is 'solid snake'"
output = ["my","name","is","'solid snake'"]

【问题讨论】：

看看stackoverflow.com/questions/366202/…
@ChrisLear 被标记为 Java，我认为它不适用于 python 的正则表达式。
无需使用正则表达式，import shlex; shlex.split(text, posix=False)。见the answer。
@WiktorStribiżew，尽管我得到了答案，但我同意该链接。我不知道那个模块！效果很好。

遍历字符串：

string = "my name is 'solid snake'"
quotes_opened = False
out = []
toadd = ''
for c, char in enumerate(string):
    if c == len(string) - 1: #is the character the last char
        toadd += char
        out.append(toadd); break
    elif char in ("'", '"'): #is the character a quote
        if quotes_opened:
            quotes_opened = False #if quotes are open then close
        else:
            quotes_opened = True #if quotes are closed the open
        toadd += char
    elif char != ' ':
        toadd += char #add the character if it is not a space
    elif char == ' ': #if character is a space
        if not quotes_opened: #if quotes are not open then add the string to list
            out.append(toadd)
            toadd = ''
        else: #if quotes are still open then do not add to list
            toadd += char
print(out)

【解决方案2】：

蛮力的方法是：

string = "my name is 'solid snake'"
output = ["my","name","is","'solid snake'"]

ui= "__unique__"

string2= string.split("'")
print(string2)

for i, segment in enumerate(string2):
    if i %2 ==1:
        string2[i]=string2[i].replace(" ",ui)
        
print(string2)

string3= "'".join(string2)

print(string3)

string4=string3.split(" ")

print(string4)

for i, segment in enumerate(string4):
    if ui in segment:
        string4[i]=string4[i].replace("__unique__", " ")

print()
print(string4)
