python打印换行符

In different programming languages such as C, C++, Java, etc. by default, the printing statements do not end with a newline.

默认情况下，在不同的编程语言（例如C，C ++，Java等）中，打印语句不以换行符结尾。

While in the case of Python, we see that the ‘print()’ function by default takes the cursor to the next line after printing the content in it. Let us look at an example where we try to print two different statements.

在使用Python的情况下，我们看到默认情况下， 'print（）'函数在将内容打印后将光标移到下一行 。 让我们看一个示例，其中我们尝试打印两个不同的语句。

print("Hello, this is Sneh.")
print("I love Python")

Output:

输出：

Hello, this is Sneh.
I love Python

This could be useful while printing the content of each ‘print()’ statement in a newline. But sometimes the user may need to print stuff in the same line.

在换行符中打印每个“ print（）”语句的内容时，这可能很有用。 但是有时用户可能需要在同一行中打印内容。

This could be achieved by using any of the two methods mentioned below for Python 2.0+ or Python 3.0+ users.

这可以通过使用以下针对Python 2.0+或Python 3.0+用户的两种方法中的任何一种来实现。

在Python 3.0+中无需换行即可打印 (Printing with no newlines in Python 3.0+)

In Python 3.0+ the ‘print()’ function comes with an additional optional argument ‘end’ which is actually nothing but the terminating string.

在Python 3.0+中 ， 'print（）'函数带有一个附加的可选参数'end' ，实际上它只是终止字符串 。

Taking the same example as above, but this time using the ‘end’ argument let’s see if we can print both the statements in a single line.

以与上面相同的示例为例，但是这次使用'end'参数，让我们看看是否可以在一行中打印两个语句。

print("Hello, this is Sneh.", end="")
print("I love Python")

Output:

输出：

Hello, this is Sneh.I love Python

So we can clearly see that just by giving any string into the print function as ‘end’ (as an argument) we can actually separate the print statements with them.

因此，我们可以清楚地看到，只要将任何字符串作为'end' （作为参数）输入到print函数中，我们实际上就可以将它们与print语句分开。

用于不使用换行符打印列表 (For printing a list without Newline)

We can similarly print the contents of a list or an Array without newlines as well. Let’s see how

我们同样可以打印列表或数组的内容而无需换行。 让我们看看如何

list1=['God','is','Good']
for i in range(3):print(list1[i],end=" ")

Output:

输出：

God is Good

在Python 2.0+中无需换行即可打印 (Printing with no newlines in Python 2.0+ )

For Python 2, we can solve the above-mentioned problem by any of the two methods. Firstly if we wan to separate the print statement contents with space( ” ” ) we can use the ‘,’ operator.

对于Python 2 ，我们可以通过两种方法中的任何一种来解决上述问题。 首先，如果我们要用空格（””来分隔打印语句的内容，我们可以使用'，'运算符。

Whereas, for other separating string we can use the sys.stdout.write a function from the Sys module in Python 2.

而对于其他分隔字符串，我们可以使用sys.stdout.write来自Python 2中Sys模块的函数。

Again, for example, using ‘,’ operator,

同样，例如，使用'，'运算符，

print("Hello, this is Sneh again!"), print("I love C++ too.")

Output:

输出 ：

Hello, this is Sneh again! I love C++ too.

Using sys.stdout.write function in place of ‘print()’,

使用sys.stdout.write函数代替'print（）'，

import sys
sys.stdout.write("Hello, this is Sneh!")
sys.stdout.write("I love C++ too.")

Output:

输出：

Hello, this is Sneh again!I love C++ too.

用于不使用换行符打印列表 (For printing a list without Newline)

使用'，'运算符 (Using ‘,’ operator)

Again looking at an example,

再看一个例子，

list1=['Learn', 'Python', 'from', 'JournalDev']
for i in range(4):print(list1[i]),

Output:

输出：

Learn Python from JournalDev

使用sys模块功能 (Using the sys module function)

Look at this example carefully,

仔细看这个例子，

import sys
list1=['Learn', 'Python', 'form', 'JournalDev']
for i in range(4):sys.stdout.write(list1[i])sys.stdout.write(",")

Output:

输出 ：

Learn,Python,from,JournalDev
