插入 ascii 转义字符时删除 python 中的双空格

Question

如何在插入 ascii 转义字符的地方删除双白space。一切都按我的意愿工作，但唯一的问题是双白色 space 在我使用转义字符的地方。

class Print(): 
    def  __init__(self, type, content, bold=False, emphasis=False, underline=False, timestamp=True):
        # Set color of the string
        if type == "info":
            self.start = "3[0m"
        elif type == "error":
            self.start = "3[91m"
        elif type == "success": 
            self.start = "3[92m"
        elif type == "warning":
            self.start = "3[93m"

        # Format style of the string
        if bold:
            self.start += "3[1m"        
        if emphasis:
            self.start += "3[3m"
        if underline:
            self.start += "3[4m"

        # Check for name and format it
        string = content.split(" ")
        formated_string = []
        for word in string:
            if word.startswith("["):
                formated_string.append("3[96m")
            formated_string.append(word)
            if word.endswith("]"):
                formated_string.append(self.start)

        self.content = " ".join(formated_string)

        # Set color and format to default values
        self.end = "3[0m"

        # Get current date and time
        stamp = datetime.now().strftime("%Y-%m-%d %H:%M:%S") + ": "

        print(f"{self.start}{stamp if timestamp == True else ''}{self.content}{self.end}")

当我将 Debug 模块导入我的代码时调用：

Debug.Print("info", "this is test [string] as example to [my] problem")

这是结果：

2021-11-03 20:16:09: this is test  [string]  as example to  [my]  problem

你可以注意到方括号前后的双白space。颜色格式不可见

Answer 1

>>> ' '.join([a for a in "this is     test [string] as example    to [my] problem".split(' ') if a])
'this is test [string] as example to [my] problem'

Answer 2

问题是，您将颜色值附加为额外元素，因此它会添加 2 个空格，因为颜色值是不可见的值，但也由空格连接。（您可以打印 formated_string 以查看添加空格的所有值）。您可以将代码更改为以下内容以修复它：

class Print():
    def __init__(self, type, content, bold=False, emphasis=False, underline=False, timestamp=True):
        # Set color of the string
        if type == "info":
            self.start = "3[0m"
        elif type == "error":
            self.start = "3[91m"
        elif type == "success":
            self.start = "3[92m"
        elif type == "warning":
            self.start = "3[93m"

        # Format style of the string
        if bold:
            self.start += "3[1m"
        if emphasis:
            self.start += "3[3m"
        if underline:
            self.start += "3[4m"

        self.end = "3[0m"

        # Check for name and format it
        string = content.split(" ")
        formated_string = []
        for word in string:
            if word.startswith("["):
                word = f"3[96m{word}"
            if word.endswith("]"):
                word = f"{word}{self.end}"
            formated_string.append(word)

        self.content = " ".join(formated_string)

        # Set color and format to default values
        self.end = "3[0m"

        # Get current date and time
        stamp = datetime.now().strftime("%Y-%m-%d %H:%M:%S") + ": "

        print(f"{self.start}{stamp if timestamp == True else ''}{self.content}{self.end}")
