仅当基于变量和特殊字符满足条件时才查找和替换值

# 示例代码
variable = "value"
special_char = "@"

if variable == "value" and special_char == "@":
    # 执行查找和替换操作
    result = text.replace("old_value", "new_value")

// 示例代码
var variable = "value";
var special_char = "@";

if (variable === "value" && special_char === "@") {
    // 执行查找和替换操作
    var result = text.replace("old_value", "new_value");
}

import re

variable = "value"
special_char = "@"

pattern = r"pattern_to_match"

if variable == "value" and special_char == "@":
    # 执行查找和替换操作
    result = re.sub(pattern, "new_value", text)

variable="value"
special_char="@"

if [ "$variable" = "value" ] && [ "$special_char" = "@" ]; then
    # 执行查找和替换操作
    result=$(echo "$text" | sed 's/old_value/new_value/g')
