Python，从输入中获取列表的值

Question

嗨，大家好我学习python，我有这个问题，因为没有创建1000＆＃34;如果＆＃34;功能我会这样做：

#Vari flag
print "choose flag"
print "(1) Syn"
print "(2) Ack"
print "(3) Push"
print "(4) Fin"
print "(5) Urg"
print "(6) Rst"

flag-list = ["--syn","--ack","--push","--fin","--urg","--rst"]
flag = raw_input(write number separated by comma: )

现在我会采用减号并将其转换为＆＃34; flag-list＆＃34;的文本。

Answer 1

# Note that variable names cannot contain hyphens
flag_list = ["--syn","--ack","--push","--fin","--urg","--rst"]

# This clearly has to be in quotes
user_input = raw_input("Enter numbers separated by comma:" )

# Split the user input string at the commas, and turn each element into an integer.
flag_nums = map(int, flag_num.split(','))

# List indexes start at 0, so subtract 1.
# Use brackets to access the Nth item in the list.
# This is a list comprehension.
flags = [flag_list[n - 1] for n in flag_nums]
