如何使用Python从csv文件中仅打印前10行? [英] How do I print only the first 10 lines from a csv file using Python?

问题描述

我是Python的新手，我只想打印一个巨大的csv文件的前10行.

I'm new to Python and I'm wanting to print only the first 10 lines of a huge csv file.

到目前为止，这是我的代码，可打印csv文件中的所有行

Here's my code so far that prints all of the lines in the csv file

import csv
with open('titanic.csv') as csvfile:
    reader = csv.DictReader(csvfile)
    for row in reader:
        print(row['survived'], row['pclass'], row['name'], row['sex'], row['age'])

推荐答案

您只需在10行后break.

import csv
with open('titanic.csv') as csvfile:
    reader = csv.DictReader(csvfile)
    for i,row in enumerate(reader):
        print(row['survived'], row['pclass'], row['name'], row['sex'], row['age'])
        if(i >= 9):
            break
