几种方法如下：
a = {'季青林':2,'冯思越':"很帅","汪磊":"chun",5:520,3:"你是三八"}
b = list()
for i in a.keys():
b.append(str(i))
print(",".join(b))
###############
print(",".join(sorted(list(str(key) for key in a.keys())))) #这是对其进行排序后的输出方式，加了一个sorted
###############
l = []
for i in a:
l.append(i)
print(l)
for m in l:
print(m,end=',')
答案如下
季青林,冯思越,汪磊,5,3
3,5,冯思越,季青林,汪磊
[‘季青林’, ‘冯思越’, ‘汪磊’, 5, 3]
季青林,冯思越,汪磊,5,3,
