Python将每一行写入文件

Question

I'm trying to write each line to file. Say my program output the following:

A man a bird a tree

A sleek ball in the terminal

We have our guests waiting

I want each line to be written to a new file or database. I'm assuming the concept is the same.

def break(tmp_file):
    n = 50
    with open(tmp_file) as c:
        out = []
        for line in c:
            for word in line.split():
                out.append(word)
                if word.endswith(('.', '!')) and len(out) >= n:
                    print(' '.join(out))
                    print("\n\n")
                                        f = open('save_file', "w+")
                            f.write(out)
                            f.close()
                    del out[:]

        # don't forget to flush the buffer
        if out:
            print(' '.join(out))

At the moment, It's saving all lines to same file. I expect it to save to unique file, like this:

Line1 - unique_file_1
Line2 - unique_file_2
...

Use enumerate

Ex:

def break(tmp_file):
    n = 50
    with open(tmp_file) as c:
        out = []
        for ind, line in enumerate(c, 1):
            for word in line.split():
                out.append(word)
                if word.endswith(('.', '!')) and len(out) >= n:
                    print(' '.join(out))
                    print("\n\n")
                    f = open('Line{} - unique_file_{}'.format(ind), "w+")  #File name as requested 
                    f.write(out)
                    f.close()
                    del out[:]

        # don't forget to flush the buffer
        if out:
            print(' '.join(out))

Issue is you're saving outputs in same save_file file, you can try something like this.

import datetime

n = 50
with open("infile") as c:
    out = []
    for line_number, line in enumerate(c):


        for word in line.split():
            out.append(word)
            if word.endswith(('.', '!')) and len(out) >= n:
                print(' '.join(out))
                print("\n\n")

        if out:
            f = open(str((line_number+1).txt), "w+")
            f.write(' '.join(out))
            f.close()
            del out[:]

# don't forget to flush the buffer
if out:
    print(' '.join(out))
