If you have high performance requirements, and the Python version is above 3.6, we recommend using F-string. For example, the following f-string readability is much better than the + sign:" "name='Hadoop' Age= 12Gender='Femal'a= f'name: {name} Age: {ages} Gender: {gender}'b='Name:'+ name +'\ t Age:'+ STR (age) +'\ t Sex:'+GenderPrint(a)Print(b)" "Joins and f-string are recommended when connecting a large number of strings, and depending on the version of Python you use and the readability requirements you choose.
