好的,以下是Python的实现代码:
```python
string = "I think hope is a good thing."
index = string.find('hope')
if index != -1:
result = string[:index] + 'love' + string[index+4:]
print(result)
else:
print("字符串中未找到'hope'")
```
输出结果为:`I think love is a good thing.`。

寻找字符串"I think hope is a good thing."中字符串"hope"的下标,并将字符串中的hope替换成freedom,将新字符串保存到变量result中并在屏幕上输出。(使用replace方法)
好的,我理解了你的要求。下面是代码实现:
```
# 定义原始字符串
string = "I think hope is a good thing."
# 寻找字符串 hope 的下标
index = string.index("hope")
# 将字符串 hope 替换成 freedom
result = string.replace("hope", "freedom")
# 输出结果
print("原始字符串:", string)
print("新字符串:", result)
```
输出结果为:
```
原始字符串: I think hope is a good thing.
新字符串: I think freedom is a good thing.
```
