找到所有可能性循环 - 函数尝试

Question

我写了代码，现在我遇到了问题，代码只找到第一个值(例如只有img，我们也有img2，但它去了另一张图片(并只复制一个，但我们有2种可能性。

for i in df_list:
img = (filepath + i + ".jpg")
img2 = (filepath + i + "-1" + ".jpg")
img3 = (filepath + i + "-2" ".jpg")
img4 = (filepath + i + "-3" + ".jpg")
img5 = (filepath + i + "-4" + ".jpg")
img6 = (filepath + i + " -5" + ".jpg")
try:
shutil.copy(img, newpath, follow_symlinks=True)
except:
try:
shutil.copy(img6, newpath, follow_symlinks=True)
except:
try:
shutil.copy(img2, newpath, follow_symlinks=True)
except:
try:
shutil.copy(img3, newpath, follow_symlinks=True)
except:
try:
shutil.copy(img4, newpath, follow_symlinks=True)
except:
try:
shutil.copy(img5, newpath, follow_symlinks=True)
except:
with open("C:/Users/"+user+"/Desktop/J/"+datum+"/"+"Napake.txt", "a") as text_file:
print("Slika za ident {} ne obstaja.n".format(i), file=text_file)

我帮忙，谢谢你的回答。

而不是复制try，除了你可以循环文件编号并尝试复制每个文件。 如果出现异常，则打印错误。

save_path = "C:/Users/" + user + "/Desktop/J/" + datum + "/" + "Napake.txt"
for folder in df_list:
for index in range(6):
if index == 0:
img = filepath + folder + ".jpg"
else:
img = f"{filepath}{folder}-{index}.jpg"
try:
shutil.copy(img6, newpath, follow_symlinks=True)
with open(save_path, "a") as text_file:
text_file.write(f"Slika za ident {folder}-{i} ne obstaja.n")
except Exception as e:
print('could not copy file')
print(e)

我还建议看看这个答案，看看如何复制目录中的所有文件。
