怎么让a,b,c,变成{a},{b},{c}？不是这个{'a'}{'b'}{'c'} 。

# 虽然但是......

s = '''a,b,c'''
for t in s.split(','):
    print({t}, end='')

# 怎么去除左右两点'x'

s = '''a,b,c'''
r = ''
for t in s.split(','):
    r = r + '{%s}' % t + ','
print(r[:-1])

print(f'{{{t}}}',end=',')

s = '''a,b,c'''
ss=','.join(['{'+x+'}' for x in s.split(',')])
x,y,z=eval(ss)
