blocks|key|478608|text|python的内置打印功能隐式地将'\n‘作为结束字符。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|478609|print(*objects,+sep='+',+end='\n',+file=sys.stdout,+flush=False)：

python's <a href="https://docs.python.org/3/library/functions.html#print" rel="nofollow noreferrer">built-in print function</a> has '\n' as end character implicitly.
<blockquote>
<code>print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)</code>:
Print objects to the text stream file, separated by sep and followed by end. sep, end, file and flush, if present, must be given as keyword arguments
</blockquote>
So, every time you run <code>print()</code> there is a '<code>\n</code>' character that gets printed implicitly unless you override the behavior by passing <code>end=</code> to it. (like <code>end=''</code> for instance)

blocks|key|1453830|text|您的代码可以等效地编写：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1453831|#

Your code can be equivalently written:

<pre><code>#
print()
print(‘Some things I learned so far:’)
print()
#
</code></pre>

blocks|key|1453921|text|默认情况下，print将新行放在末尾，若要修改此行为，可以使用end=设置end参数“”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1453922|示例：|1453923|print("this+will+use+2+lines+\n")
print("this+will+use+1+line")

By default print put a new line at the end, to modify this behavior you can set the end parameter with end=""

Example:

<pre><code>print("this will use 2 lines \n")
print("this will use 1 line")
print("this will use 1 line \n", end="")
</code></pre>

blocks|key|482892|text|默认情况下，打印转到下一行。试一试|type|unstyled|depth|inlineStyleRanges|entityRanges|data|482893|print("+",end+=+"")|code-block|syntax|javascript|482894|这样你就能看得更清楚。|482895|另外，选项卡跳到下一个块。一个块通常是4个空格。试试这个，注意。是：|482896|print("\t",+end=".\n")
print("A\t",+end=".\n")
print("ABC\t",+end=".\n")
print("ABCD\t",+end=".\n")|482897|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|D|7|S|8|@]|9|@]|A|$E|F]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

print by default goes to the next line. try 

<pre><code>print(" ",end = "")
</code></pre>

so you can see '\t' more clearly. 

Also, tab jumps to the next block. A block is usually 4 spaces.
Try this and notice where the . is:

<pre><code>print("\t", end=".\n")
print("A\t", end=".\n")
print("ABC\t", end=".\n")
print("ABCD\t", end=".\n")
</code></pre>

blocks|key|1453978|text|语句print('\t')正在打印一个选项卡，然后返回到下一行，因为默认的打印函数会自动添加一个换行符。所以你看不见标签，但它就在那里。当将\n添加到打印的字符串末尾时，除了默认的行返回之外，它还会添加一行返回。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1453979|若要删除默认行返回，请指定print函数的“end”参数：|1453980|print('abcd\n',+end='')|1453981|这将只包含一行返回。|1453982|entityMap^0|2|B|0|0|0|N|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|R|8|@$9|S|A|T|B|C]]|D|@]|E|$]]|$1|J|3|K|5|6|7|U|8|@]|D|@]|E|$]]|$1|L|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|M|$]]

The statement <code>print('\t')</code> is printing a tab, then returning to the next line, as the default print function automatically adds a newline. So you can't see the tab, but it is there. When you add \n to the end of the string you print, it adds a line return in addition to the default line return. 

To remove the default line return, specify the 'end' parameter of the print function:

<code>print('abcd\n', end='')</code> 

This will only include one line return.

blocks|key|482926|text|"\n"字符是换行符，当您打印"\n"时，它会将光标设置为新行。默认情况下，print总是在最后设置一个新行。但是，您可以通过将end参数的值设置为空字符串来更改该行为。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|482927|print("hello",+end="")|code-block|syntax|javascript|482928|"\t"是tab字符|482929|for+i+in+range(20):

<code>&quot;\n&quot;</code> character is a newline character and when you print <code>&quot;\n&quot;</code> it sets the cursor to a new line. <code>print</code> always sets a new line in the end by default. But you can change that behavior by setting the value of <code>end</code> argument to an empty string.
<pre><code>print(&quot;hello&quot;, end=&quot;&quot;)
</code></pre>
<code>&quot;\t&quot;</code> is a <code>tab</code> character
<pre><code>for i in range(20):
 print(&quot;current number is\t&quot;, I)

# current number is 1
# current number is 2
# current number is 3

Since print() does give an <code>'\n'</code> string at the end of each output the command <code>print('\n')</code> gives the commandline string <code>'\t\n'</code>.

For more details please see the following well documented post <a href="https://stackoverflow.com/questions/493386/how-to-print-without-newline-or-space">Link</a>

I do not understand why when inputing a space between the code with \t gives one space of line between the 'green' and 'Some things I learned so far:' output. When I use \n it gives two spaces inbetween. Shouldn't the space be the same for either \t and \n? I know that \t does tab and \n is new line. but I do not understand how \n does two spaces inbetween
Code is:

<pre><code>fav_num = {
 'rachel':'blue',
 'hannah':'green',
}
print(fav_num['rachel'])
print(fav_num['hannah'])
#6-3
coding_glossary = {
 'list':'mutable type where you can store info',
 'tuple':'immutable type similar to list',
 'string':'simple line of code'
}
print('\t')
print('Some things I learned so far: \n')
print('What a list is:')
print(coding_glossary['list'])
</code></pre>

Output is :

<pre><code>blue
green

Some things I learned so far: 

What a list is:
mutable type where you can store info

Process finished with exit code 0
</code></pre>

Python \n gives two spaces in between output and \t gives one

我不明白为什么用\t在代码之间输入一个空格，在“绿色”和“到目前为止我学到的一些东西：”输出之间留出一行空间。当我使用\n时，它在中间有两个空格。空间不应该是相同的\t和\n吗？我知道\t做制表符\n是新行。但我不明白代码之间的两个空格是如何做到的：fav_num = {    'rachel':'blue',    'hannah':'green',}print(fav_num['rachel'
