python之返回一个字符串，如何格式化输出

我有代码分析一个 csv 文件并返回一列的最大值和同一行中另一列的值作为最大值。我在格式化输出时遇到问题。

代码:

import csv 
 
def bigQuake(inputfilename): 
    with open(inputfilename,"r") as input_file: 
        reader = csv.reader(input_file) 
 
        maxvalue = 0.0 
        location = None 
        for line in reader: 
            try: 
                p = float(line[4]) 
                if p > maxvalue: 
                    maxvalue = p 
                    location = line[13] 
            except ValueError: 
               pass 
    return "The largest earthquake was a", maxvalue, "magnitude earthquake", location + "." 

当前输出是什么样的:

>>> bigQuake("file.csv") 
>>> ('The largest earthquake was a', 6.3, 'magnitude earthquake', '13km N of Kunisaki-shi, Japan.') 

我想要的:

>>> bigQuake("file.csv") 
>>> 'The largest earthquake was a 6.3 magnitude earthquake 13km N of Kunisaki-shi, Japan.' 

我该如何解决这个问题？

请您参考如下方法:

使用这个，

return "The largest earthquake was a" + str(maxvalue) + "magnitude earthquake" + location + "." 

或

return "The largest earthquake was a %s magnitude earthquake %s." % (maxvalue, location)
