缩进中制表符和空格的使用不一致 Python

Question

我不断在 sys.argv[1] 和 print 命令前面收到错误。

code定义 run_example():

global total_packet_count, total_bytes_count

try:
sys.argv[1]
dmp_file = sys.argv[1]
fp_dmp_file = open(dmp_file)
except Exception as e:
print ('Error: please supply pcap filename!\n')
return

ts = time.time()
src_ip = '1.2.3.4'
src_port = 99
dst_ip = '5.6.7.8'
dst_port = 199
protocol = 'tcp'

print_packet_info(ts, src_ip, src_port, dst_ip, dst_port, protocol, 1000, 64)

print_summary(100, 1500, 1500 / 100)

fp_dmp_file.close()

如果名称== '主要'：run_example()
