python print()函数中的新行 [英] New line in python print() function

问题描述

我正在使用Python 2.7.3，并且正在编写一个脚本，该脚本打印任何用户定义文件的十六进制字节值.它可以正常工作，但有一个问题:每个值都被打印在新的一行上.是否可以使用空格而不是换行来打印值?

I am using Python 2.7.3 and I am writing a script which prints the hex byte values of any user-defined file. It is working properly with one problem: each of the values are being printed on a new line. Is it possible to print the values with spaces instead of new lines?

例如，代替

61

62

我想拥有61 62.

下面是我的代码(..txt是一个包含文本'abcd'的文件):

Below is my code (..txt is a file which contains the text 'abcd'):

#!usr/bin/python
import os
import sys
import time

filename = raw_input("Enter directory of the file you want to convert: ")

f = open(filename, 'rb')
fldt = f.read()
lnfl = len(fldt)
print "Length of file is", lnfl, "bytes. "
orck = 0
while orck < lnfl:
    bndt = hex(ord(fldt[orck]))
    bndt = bndt[-2:]
    orck = orck + 1
    ent = chr(13) + chr(10)
    entx = str(ent)
    bndtx = str(bndt)
    bndtx.replace(entx, ' ')
    print bndtx

推荐答案

首先print不是Python 2中的函数，它是一条语句.

First of all print isn't a function in Python 2, it is a statement.

要禁止自动换行符，请在末尾添加,(逗号).现在将使用空格代替换行符.

To suppress the automatic newline add a trailing ,(comma). Now a space will be used instead of a newline.

演示:

print 1,
print 2

输出:

1 2

或使用Python 3的 print()函数:

Or use Python 3's print() function:

from __future__ import print_function
print(1, end=' ') # default value of `end` is '\n'
print(2)

您可以清楚地看到print()函数的功能强大得多，因为我们可以指定要用作end而不是固定空格的任何字符串.

As you can clearly see print() function is much more powerful as we can specify any string to be used as end rather a fixed space.
