| The string prefixes u and f can't used together, for example: >>> age = 30 >>> s = uf'年龄：{age}' File "", line 1 s = uf'年龄：{age}' ^ SyntaxError: invalid syntax >>> | ||

| The string prefix u is used exclusively for compatibility with Python 2. It helps writing code that works in Python 2 and Python 3. The string prefix f is not compatible with Python 2. If you use it, you no longer have reasons for using the string prefix u. |
