.append在嵌套if中没有按顺序添加

Question

我正试图找到特定的值，编辑它们并将它们写回列表。如果值不在列表中，则按原样追加。

columns_list = ["Section", "String ENG", "AZ", "RU"]
loco_df = pd.read_csv("loco_auto_in.csv", usecols=columns_list)

main_file = open('bayg_t.txt','r')
eng_txt_list = []
az_txt_list = [] 
for line in main_file:
eng_txt_list.append(line)
for i in loco_df["String ENG"]:
for x in eng_txt_list:
tr_strings = re.findall(r'msgid+."(.*?)"', x)
if tr_strings:
if i == tr_strings[0]: 
e_x = x.replace(tr_strings[0], "00000000000xxxxx0000")
az_txt_list.append(e_x)
elif x not in az_txt_list: 
az_txt_list.append(x)

elif x not in az_txt_list: 
az_txt_list.append(x)

print(az_txt_list)

问题是:它总是添加编辑"00000000000xxxxx000 "然而，在列表的末尾，在列表的中间有匹配项。我已经检查过了，但看不出原因。

提前谢谢你。

问题嵌套为。

for i in loco_df["String ENG"]:
string_list.append(i)

for x in eng_txt_list:
tr_strings = re.findall(r'msgid+."(.*?)"', x)
if tr_strings:
if tr_strings[0] in string_list: 
print("Matched!")
e_x = x.replace(tr_strings[0], "00000000000xxxxx0000")
az_txt_list.append(e_x)
elif x not in az_txt_list: 
az_txt_list.append(x)

elif x not in az_txt_list: 
az_txt_list.append(x)
print(az_txt_list)
