fhandle: IO = open("seqs.txt","r")
list_of_let: List[str] = []
for items in fhandle:
spltl: List[str] = items.split("\t")
new_let: str = str(spltl[0])
list_of_let.append(new_let)
print(list_of_let)

你可以使用str.split()。您不需要指定\t字符，split会自动使用空格进行分割：
with open('your file.txt', 'r') as f_in:
for line in map(str.strip, f_in):
# 跳过空行：
if line == "":
continue
_, part_2 = line.split(maxsplit=1)
print(part_2)

英文:
You can use str.split(). You don't have to specify the \t char, split will automatically work with whitespaces:
with open('your file.txt', 'r') as f_in:
for line in map(str.strip, f_in):
# skip empty lines:
if line == "":
continue
_, part_2 = line.split(maxsplit=1)
print(part_2)
