改成这样：

fo = open("PY202.txt","w")
data = input("请输入课程名及对应的成绩：")  
a={}
while data:
    xueke,chengji=data.split(' ')
    a[xueke]=int(chengji)
    data = input("请输入课程名及对应的成绩：")
c=list(a.items())
c.sort(key = lambda x : x[1], reverse=True)
zuigaoxk=c[0][0]
zuigaofen=c[0][1]
zuidixk=c[-1][0]
zuidifen=c[-1][1]
zongfen=0
for i in range(len(c)):
    zongfen += int(c[i][1])
pingfen=zongfen/len(c)
fo.write("最高分课程是{} {}, 最低分课程是{} {}, 平均分是{:.2f}".format(zuigaoxk,zuigaofen,zuidixk,zuidifen,pingfen))
fo.close()
