Python string strip()用法及代碼示例

strip()是Python編程語言中的內置函數，該函數返回刪除了前導和尾隨字符的字符串的副本(基於傳遞的字符串參數)。
用法:

string.strip([chars])
參數：
There is only one optional parameter in it:
1)chars - a string specifying 
the set of characters to be removed. 

If the optional chars parameter is not given, all leading 
and trailing whitespaces are removed from the string.
返回值：
Returns a copy of the string with both leading and trailing characters removed.

# Python3 program to demonstrate the use of 
# strip() method   
  
string = " geeks for geeks " 
  
# prints the string without stripping 
print(string)  
  
# prints the string by removing leading and trailing whitespaces 
print(string.strip())    
  
# prints the string by removing geeks 
print(string.strip(' geeks'))

輸出：

 geeks for geeks 
geeks for geeks
for

錯誤：
當我們嘗試剝離字符串以外的任何內容時，都會出現運行時錯誤。係統給出的輸出顯示

# Python3 program to demonstrate the use of 
# strip() method error 
  
string = " geeks for geeks "
list =[1, 2, 3]  
  
# prints the error message 
print(list.strip()) 

輸出：

Traceback (most recent call last):
  File "/home/1bdead5a6ad1dbb0db1c6a2663874e4c.py", line 8, in 
    print(list.strip()) 
AttributeError:type object 'list' has no attribute 'strip'

實際應用：
給定一個字符串，請從開頭和結尾刪除單詞“The”的出現。

# Python3 program to demonstrate the practical application 
# strip()  
  
  
string = " the King has the largest army in the entire world the" 
  
# prints the string after removing the from beginning and end 
print(string.strip(" the"))

輸出：

King has the largest army in the entire world
