为了从字符串中删除空格和尾随空格，Python 提供了 strip([str]) 内置函数。此函数在删除空格（如果存在）后返回字符串的副本。否则返回原始字符串。

string = "  javatpoint "  
string2 = "    javatpoint        "  
string3 = "       javatpoint"  
print(string)  
print(string2)  
print(string3)  
print("After stripping all have placed in a sequence:")  
print(string.strip())  
print(string2.strip())  
print(string3.strip())  

javatpoint 
    javatpoint        
       javatpoint

After stripping all have placed in a sequence:

javatpoint

javatpoint

javatpoint
