python之为什么我的程序将 function convert at 0x02DE8C00> 写入我的文件

def convert(score):  
    if score >= '90': 
        msg = "Congratulations! You earned an A!" 
        (msg) 
 
    elif score >= '80': 
        msg = "You earned a B; good job!" 
        (msg) 
 
    elif score >= '70': 
        msg = "You earned a C; looks like you need to study a little harder." 
        (msg) 
 
    elif score >= '60': 
        msg = "You earned a D; maybe you should consider tutoring" 
        (msg) 
 
    else: 
        score < '60' 
        msg = "I'm sorry; you failed." 
        (msg) 
 
 
    return convert 
 
def main(): 
    infilename = input("Please enter the name of the input file: ")  
    outfilename = input("Please enter the name of the output file: ") 
 
    infile = open(infilename,"r") 
    outfile = open(outfilename,"w") 
 
    for line in infile:  
        msg = convert(line)  
        print(msg,file=outfile) 
 
    infile.close() 
    outfile.close() 
 
main() 

成绩本应打印到文件中，但当我打开文件时，它只显示:<function convert at 0x02DE8C00> .如果我运行代码，并且不尝试将它打印到文件中，它会工作正常。

好吧，他们想让我添加更多细节，但我真的想不出还有什么要添加的，我想你明白了。

这次我做错了什么？

请您参考如下方法:

您的函数返回自身 (return convert) 而不是 msg。
