20230401在win10下复制粘贴python代码的问题【TAB惹的祸】
2023/4/1 16:07
习惯使用TAB按键而不是4个空格来分割代码块！
在WIN7下调通的python代码，生成一个使用ffmpeg来合并ts切片文件的脚本。
但是在WIN10下异常了！
temp = ""
url = "ffmpeg -i \"concat:"
#for n in range(1,10):
for n in range(1,999):
#temp = "./1574/%03d.ts"%n
temp = "%03d.ts|"%n
url = url + temp
#print(temp)
#print(url)
temp = "%03d.ts"%(n+1)
url = url + temp
temp = "\" -c copy output1.ts"
url = url + temp
f=open("./1574/1.bat","w")
f.write(url)
f.close()

将TAB按键使用4个空格替代即可：
temp = ""
url = "ffmpeg -i \"concat:"
#for n in range(1,10):
for n in range(1,999):
#temp = "./1574/%03d.ts"%n

url = url + temp
