如何序列化列表并将其写入 Python 中的 txt 文件

Question

a Python newbie here. Im learning Python and stuck at the below problem. I want my output file to be serialized. Please help.

#say the list is l = ['h','e','l','l','o']
filename = input("Input File name: ")
with open(filename+".txt",'w') as f:
    for items in l:
        f.write(f"{items}\n")

How do I add serial numbers to my output. I know to enumerate but how to add enumerate to the output file.

Answer 1

l = ['h','e','l','l','o']
filename = input("Input File name: ")
with open(filename+".txt",'w') as f:
    for index,items in enumerate(l,1):
        f.write(f"{index} {items}\n")

In enumerate first parameter is the iterable that is l and second parameter is from where you want to start your index

Answer 2

Just do this:-

for i in range(len(l)):
    f.write(f'{i+1}.{l[i]}\n')        #l here is your list
