A summary of the usage of the Python strip () function and the Split function

Strip function prototypes

declaration : S is a string, RM is a sequence of characters to be deleted

S.strip (RM) Remove the characters from the beginning and end of the s string in the RM delete sequence

S.lstrip (RM) Delete the character in the S string at the beginning of the RM delete sequence

S.rstrip (RM) Removes the character from the end of the S string that is located in the RM delete sequence

Note :

1. When RM is empty, the default is to remove the whitespace characters (including ' \ n ', ' \ R ', ' \ t ', ')

For example:

2. The RM delete sequence here is deleted as long as the character on the edge (beginning or end) is within the delete sequence.

For example:

Split usage of strings

Description
There is no character type in Python, only a string, the character here is a string that contains only one character!!!

Split returns a list.

1. Divide by a character, such as '. '

1234	str= (‘www.google.com‘)print strstr_split = str.split(‘.‘)printstr_split

The results are as follows:

2. Divide by one character and divide n times. If you press '. ' Split 1 times

?

1234	str= (‘www.google.com‘)print strstr_split = str.split(‘.‘，1)printstr_split

The results are as follows:

3. Split by a string. such as: ' | | '

?

1234	str= (‘WinXP||Win7||Win8||Win8.1‘)print strstr_split = str.split(‘||‘)printstr_split

The results are as follows:

4. Divide by a string and divide n times. such as: Press ' | | ' Split 2 times

?

1234	str= (‘WinXP||Win7||Win8||Win8.1‘)print strstr_split = str.split(‘||‘,2)printstr_split

The results are as follows:

5. Divide by a character (or string), divide n times, and assign the completed string (or character) of the partition to a new (n+1) variable. (Note: See opening instructions)
such as: Press '. ' Splits the character, splits it 1 times, and assigns the split string to 2 variables Str1,str2

?

1234	url =(‘www.google.com‘)str1, str2 = url.split(‘.‘, 1)print str1printstr2

The results are as follows:
