for st in lineInfo[:]['st']: TypeError: list indices must be integers or slices, not str

Question

有知道这是怎么回事吗？源代码在下面
def save_file(filename, lineInfo):
#print("开始写入文件......")
with open(filename, 'a', encoding='utf-8') as f:
for st in lineInfo['st']:
f.write(st['name'] + " " + st['lat'] + " " + st['lon'] + "\n")

Answer 1

lineInfo[:]['st']列表索引必须是整数或切片，不能是字符。
