笨办法学python 13题:pycharm 运行
笨办法学python 13题
代码:
1 # -*- coding: utf-8 -*- 2 from sys import argv 3 4 # argv--argument variable 参数变量 5 script, first, second, third = argv 6 7 print "the script is called:", script 8 9 print "your first variable is:", first 10 11 print "your second variable is:", second 12 13 print "your third variable is:", third
pycharm直接运行时,会报:ValueError: need more than 1 value to unpack
意思是:还需要一个值才能解包
使用pycharm正常运行ex13:edit configurations--parameters输入参数--apply--运行
然后重新点运行,正常运行,并输出结果
ps:14题同样的运行方式:
user_name作为参数填入parameters中,然后正常运行,可以在控制台进行输入输出显示。
