我在比较时遇到了一个非常奇怪的问题。
我想解码python脚本参数,存储它们并分析它们。在以下命令中,-r选项应用于确定要创建的报告类型。
python脚本启动:
%run decodage_parametres_script.py -r junit,html
python脚本选项解析用于填充字典,结果是: current_options:
{'-cli-no-summary': False, '-cli-silent': False, '-r': ['junit', 'html']}
然后我想测试-r选项,这里是代码:
for i in current_options['-r']:
# for each reporter required with the -r option:
# - check that a file path has been configured (otherwise set default)
# - create the file and initialize fields
print("trace i", i)
print("trace current_options['-r'] = ", current_options['-r'])
print("trace current_options['-r'][0] = ", current_options['-r'][0])
if current_options['-r'][i] == 'junit':
# request for a xml report file
print("request xml export")
try:
xml_file_path = current_option['--reporter-junit-export']
print("xml file path = ", xml_file_path)
except:
# missing file configuration
print("xml option - missing file path information")
timestamp = get_timestamp()
xml_file_path = 'default_report' + '_' + timestamp + '.xml'
print("xml file path = ", xml_file_path)
if xml_file_path is not None:
touch(xml_file_path)
print("xml file path = ", xml_file_path)
else:
print('ERROR: Empty --reporter-junit-export path')
sys.exit(0)
else:
print("no xml file required")
我想尝试默认报告生成,但我甚至不打印("请求xml导出")行,这是控制台结果:
trace i junit
trace current_options['-r'] = ['junit', 'html']
trace current_options['-r'][0] = junit
我猜这可能是一个类型问题,我尝试了以下测试:
In [557]: for i in current_options['-r']:
...: print(i, type(i))
...:
junit <class 'str'>
html <class 'str'>
In [558]: toto = 'junit'
In [559]: type(toto)
Out[559]: str
In [560]: toto
Out[560]: 'junit'
In [561]: toto == current_options['-r'][0]
Out[561]: True
所以我的行断言if current_options['-r'][i] == 'junit'
:应该最终开始为真,但事实并非如此。
我错过了一些小事吗? :(
有人可以帮助我吗?
答案 0 :(得分:0)
您正在按字符串数组进行迭代
for i in current_options['-r']:
在你的情况下i
将是:
第一次迭代时junit
下次迭代时html
并且您的if条件(从解释器角度来看)将如下所示:
if current_options['-r']['junit'] == 'junit':
而非预期:
if current_options['-r'][0] == 'junit':
解决方案1:
您需要遍历range(len(current_options['-r']))
解决方案2
改变你的比较器:
从
if current_options['-r'][i] == 'junit':
到
if i == 'junit':
