① 直接使用replace,原理如上面解法 ② 使用split+join class Solution(object): def replace_space2(self, str): if not str or len(str) == 0 : return False str = str.replace(' ', '%20') return str def replace_space3(self, str): i
string.partition(str) 有点像 find()和 split()的结合体,从 str 出现的第一个位置起,把字符串 string 分成一个 3 元素的元组 (string_pre_str,str,string_post_str),如果 string 中不包含str 则 string_pre_str == string. string.replace(str1, str2, num=string.count(str1)) 把string 中的 str...
string.replace(str1, str2, num=string.count(str1)) 把string 中的 str1 替换成 str2,如果 num 指定,则替换不超过 num 次. string.rfind(str, beg=0,end=len(string) ) 类似于 find() 函数,返回字符串最后一次出现的位置,如果没有匹配项则返回 -1。 string.rindex( str, beg=0,end=len(stri...
path='hive://ads/training_table'namespace=path.split('//')[1].split('/')[0]# 返回'ads'table=path.split('//')[1].split('/')[1]# 返回'training_table'data=query_data(namespace,table) 此外,常见的函数还有: string.strip(str),表示去掉首尾的str字符串; string.lstrip(str),表示只去掉...
replace(old, new [, max])把 将字符串中的 old 替换成 new,如果 max 指定,则替换不超过 max 次。 27 rfind(str, beg=0,end=len(string))类似于 find()函数,不过是从右边开始查找. 28 rindex( str, beg=0, end=len(string))类似于 index(),不过是从右边开始. 29 rjust(width,[, fillchar])...
In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
Themethod is used to remove whitespace from the start and end of a string. For removing whitespace from the entire string,replace()can be used, and for more sophisticated patterns, you can use regular expressions via theremodule. How to remove space in Python print?
We will now use thereplace()function to replace our newline character with space. We pass our string as a parameter to the function and store the new resultant string in a new variable. string2=string1.replace("\n"," ") The above code will replace all the newline characters in our ...
result = remove_spacee(string) # Example 10: Using isspace() method # To remove spaces from a string def remove(string): result="" for i in string: if(not i.isspace()): result+=i return result result = remove(string) 2. Remove Spaces from a String Using replace() Method ...
