Answer 1

newstring =string.replace(python,Python)

改成

newstring =string.replace('python','Python')

'python' 和'Python' 是字符串要用引号包裹

find没有找到会返回-1，要判断!=-1
你题目的解答代码如下：

string = "Life is short I use python"
if string.find("python")!=-1:  # find没有找到会返回-1，要判断!=-1
    new_string =string.replace('python','Python')
    print(new_string)
else:
    print(string)

如有帮助，望采纳！谢谢!
