subprocess.run() issues with mkdir

Question

我在subprocess.run()上遇到了麻烦。

我尝试在WindowsSubsystemForlinux1 WSL1应用程序中创建一个新目录。

目录名必须为(例如):a0_998.0784269595375(逗号后总是13位数字)。这组数字是Python函数的输出。我有的:

def SMILEI(I):
os.chdir("/home/velenos14/PICsims/github/SMILEI_correctTunnelBSIrate/Smilei/SIMRESULTS/GPs_trial_Xenon_noOAM")
a0 = "%.13f" % a0_from_IntensityWcm2(I) # a0_from_IntensityWcm2() is a function
subprocess.run(['dirname="a0_"', 'mkdir' '-p' '$dirname'], check=True, text=True) # PermissionError: [Errno 13] Permission denied: 'dirname="a0_'

我做错了什么?BASH命令(用于工作和执行任务)如下:

for ((i = 1; i <= 15000; i++))
do
index=$((i))
a0=$(awk "NR==${index} { print $2 }" Intensity_Wcm2_versus_a0_10_20_10_25_range.txt)
dirname="a0_${a0}"
mkdir -p $dirname
cd $dirname
done

据我所知，您希望将dirname参数作为环境变量传递给mkdir子进程。

相反，事先构造dirname变量并像这样传递给subprocess.run:

def SMILEI(I):
os.chdir("/home/velenos14/PICsims/github/SMILEI_correctTunnelBSIrate/Smilei/SIMRESULTS/GPs_trial_Xenon_noOAM")
dirname = "a0_%.13f" % a0_from_IntensityWcm2(I)
subprocess.run(["mkdir", "-p", dirname], check=True, text=True)
