例：将train5bottle.names的每行内容提取出来转化成数组
转换代码：
result = []
with open(r'E:HISIdarknet-masterbuilddarknetx64datatrain5bottle.names' ,'r') as f:
for line in f:
result.append(line.strip().split(',')[0]) #a.append(b)：是将b原封不动的追加到a的末尾上，会改变a的值
#strip()用于移除字符串头尾指定的字符（默认为空格或者换行符）或字符序列
print(result)
print(result[0])
#运行结果：
['0degree', '6degree', '12degree', '18degree', '24degree', '30degree', '36degree', '42degree', '48degree', '54degree', '60degree', '66degree', '72degree', '78degree', '84degree', '90degree', '96degree', '102degree', '108degree', '114degree', '120degree', '126degree', '132degree', '138degree', '144degree', '150degree', '156degree', '162degree', '168degree', '174degree', '180degree']
0degree
