英文:
Stop python loop (List)
问题
我是Python新手。我有一个循环：
# todaystr给出系统日期的字符串，例如202307if not os.path.exists(os.path.join(folder, todaystr)):os.makedirs(os.path.join(folder, todaystr))for f in os.listdir(folder):if not (f.startswith(todaystr) and f.endswith(".hl7")):breakfor g in os.listdir(folder)[:4]:if g.endswith('.hl7') and g.startswith(todaystr):shutil.move(os.path.join(folder, g), destination)
数据列表：
'202307','20230713-0955.hl7','20230713-0955.hl7','20230713-0955.hl7','20230713-0955.hl7','20230713-0955.hl7','202307XY'
循环应该在列表不再包含以"202307"开头且以"hl7"结尾的数据时停止。问题是有一个名为"202307"的文件夹，所以它立即停止。
谢谢
对不起我的英语不好。
我确定我的if子句内部有问题。
英文:
Im new to python. I have a loop
#todaystr gives string of sysdate e.g. 202307if not os.path.exists(os.path.join(folder, todaystr )):os.makedirs(os.path.join(folder, todaystr ))for f in os.listdir(folder):if not ( f.startswith(todaystr) and f.endswith("hl7")) :breakfor g in os.listdir(folder)[:4] :if g.endswith('.hl7') and g.startswith (todaystr) :shutil.move(os.path.join(folder, g),destination)
list data:
'202307','20230713-0955.hl7','20230713-0955.hl7','20230713-0955.hl7','20230713-0955.hl7','20230713-0955.hl7','202307XY'
The loop should stop as soon as the list contains no data starting with "202307" and ending with "hl7". The Problem is that there is a folder "202307" so he stops instantly.
Thank you
Sorry for my bad english.
Im sure i have a Problem inside my if clause

看起来你想要类似这样的东西：
import osfolder = "/path/to/folder"for f in os.listdir(folder):print(f)if not (f.startswith("202307") and f.endswith("hl7")):break
英文:
It sounds like you want something like this:
import osfolder = "/path/to/folder"for f in os.listdir(folder):print(f)if not (f.startswith("202307") and f.endswith("hl7")):break

你可以使用glob函数来获取与模式匹配的所有文件，然后确定是否存在一个值。
它可以从glob模块导入，或者使用pathlib.Path类的glob方法。
import osfolder = "/path/to/folder"print(glob.glob("202307*hl7", root_dir=folder))"""import pathlibprint(list(pathlib.Path(folder).glob("202307*hl7")))"""
英文:
You can use the glob function to get all the files that match the pattern, and then determine whether there is a value.
It can be imported from the glob module, or using the glob method of the pathlib.Path class.
import osfolder = "/path/to/folder"print(glob.glob("202307*hl7", root_dir=folder))"""import pathlibprint(list(pathlib.Path(folder).glob("202307*hl7")))"""
