blocks|key|425229|text|replace()是python3中<class+'str'>的一种方法：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|425230|>>>+'hello,+world'.replace(',',+':')
'hello:+world'|code-block|syntax|javascript|425231|entityMap^0|0|9|I|D|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|L|$]]

<code>replace()</code> is a method of <code>&lt;class 'str'&gt;</code> in python3:

<pre><code>&gt;&gt;&gt; 'hello, world'.replace(',', ':')
'hello: world'
</code></pre>

blocks|key|639674|text|与在2.x中一样，使用str.replace()。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|639675|示例：|639676|>>>+'Hello+world'.replace('world',+'Guido')
'Hello+Guido'|code-block|syntax|javascript|639677|entityMap|0|LINK|mutability|MUTABLE|url|https://docs.python.org/library/stdtypes.html#str.replace^0|B|D|B|D|0|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@$9|V|A|W|B|C]]|D|@$9|X|A|Y|1|Z]]|E|$]]|$1|F|3|G|5|6|7|10|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|11|8|@]|D|@]|E|$K|L]]|$1|M|3|-4|5|6|7|12|8|@]|D|@]|E|$]]]|N|$O|$5|P|Q|R|E|$S|T]]]]

As in 2.x, use <a href="https://docs.python.org/library/stdtypes.html#str.replace" rel="noreferrer"><code>str.replace()</code></a>.

Example:

<pre><code>&gt;&gt;&gt; 'Hello world'.replace('world', 'Guido')
'Hello Guido'
</code></pre>

blocks|key|639682|text|试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|639683|mystring+=+"This+Is+A+String"
print(mystring.replace("String","Text"))|code-block|syntax|javascript|639684|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Try this:

<pre><code>mystring = "This Is A String"
print(mystring.replace("String","Text"))
</code></pre>

blocks|key|639704|text|ss+=+s.replace(s.split()[1],+%2Bs.split()[1]+%2B+'gy')
#+should+have+no+plus+after+the+comma+--i.e.,
ss+=+s.replace(s.split()[1],+s.split()[1]+%2B+'gy')|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|639705|unstyled|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|G|8|@]|9|@]|A|$B|C]]|$1|D|3|-4|5|E|7|H|8|@]|9|@]|A|$]]]|F|$]]

<pre><code>ss = s.replace(s.split()[1], +s.split()[1] + 'gy')
# should have no plus after the comma --i.e.,
ss = s.replace(s.split()[1], s.split()[1] + 'gy')
</code></pre>

blocks|key|639753|text|python+3中的replace()方法只需通过以下方式使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|639754|a+=+"This+is+the+island+of+istanbul"
print+(a.replace("is"+,+"was"+,+3))

#3+is+the+maximum+replacement+that+can+be+done+in+the+string#

>>>+Thwas+was+the+wasland+of+istanbul

#+Last+substring+'is'+in+istanbul+is+not+replaced+by+was+because+maximum+of+3+has+already+been+reached|code-block|syntax|javascript|639755|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

The replace() method in python 3 is used simply by:

<pre><code>a = "This is the island of istanbul"
print (a.replace("is" , "was" , 3))

#3 is the maximum replacement that can be done in the string#

&gt;&gt;&gt; Thwas was the wasland of istanbul

# Last substring 'is' in istanbul is not replaced by was because maximum of 3 has already been reached
</code></pre>

blocks|key|425370|text|简单的替换:用.replace(旧的，新的，计数)替换。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|425371|text+=+"Apples+taste+Good."
print(text.replace('Apples',+'Bananas'))++++++++++#+use+.replace()+on+a+variable
Bananas+taste+Good.++++++++++<----+Output

print("Have+a+Bad+Day!".replace("Bad","Good"))++++#+Use+.replace()+on+a+string
Have+a+Good+Day!+++++++++++++<-----+Output

print("Mom+is+happy!".replace("Mom","Dad").replace("happy","angry"))++#Use+many+times
Dad+is+angry!++++++++++++++++<-----+Output|code-block|syntax|javascript|425372|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Simple Replace:         .replace(old, new, count) .
<pre><code>text = &quot;Apples taste Good.&quot;
print(text.replace('Apples', 'Bananas')) # use .replace() on a variable
Bananas taste Good. &lt;---- Output

print(&quot;Have a Bad Day!&quot;.replace(&quot;Bad&quot;,&quot;Good&quot;)) # Use .replace() on a string
Have a Good Day! &lt;----- Output

print(&quot;Mom is happy!&quot;.replace(&quot;Mom&quot;,&quot;Dad&quot;).replace(&quot;happy&quot;,&quot;angry&quot;)) #Use many times
Dad is angry! &lt;----- Output
</code></pre>
