我正在通过学习艰难的钟,并用额外信贷进行16项工作。 我正试图阅读我用主要行动16制作的档案。 我写道:
# pylint: disable-msg=C0103
""" This script reads and prints a file set from the argv """
from sys import argv
filename = argv
txt = open(filename)
print txt.read()
我试图阅读的档案是:
Derp Derp
Reading this file
Will it work?
我收到这一错误:TypeError: coercing to Unicode: need string or.5/53/, list found,但无法确定我的档案是一份清单,而不是拼凑。
To debug, 尝试印刷filename
argv is a list of evidence to their script. 第一种论点是:argvl。 引证:
from sys import argv
txt = open(argv[1])
print txt.read()
<>Important note:, 几乎总是名单上的第一个项目是0th items,argv, 这是一项例外,因为0th 的论点是您的描述。
我也面临同样的错误,但用本法典解决了这一错误:
from sys import argv
txt = open(argv[1])
print txt.read()
