This article mainly introduces how to use the python splicing function, which is very detailed and has a certain reference value. Friends who are interested must finish reading it!

1. Split divides the large string into several substrings.

# a.split () # cut (by default split by space) You can also specify the parameter to cut according to XX (but the specified parameter will be cut off) msg = 'The day is a sunny day'result1 = msg.split () print (result1) result2 = msg.split (' y') # specify the parameter to cut off print (result2) result3 = msg.split (maxsplit=2) # represents a total of 2 cuts from the left print (result3) output: ['The',' day', 'is',' 'sunny',' day'] ['The da',' is a sunn', 'da','] ['The',' day','is a sunny day']

2. Partition looks from the left and returns the tuple according to the specified delimiter.

It contains: the separator on the left and the delimiter on the right.

# a.partition () # starts from the left and returns a tuple according to the specified delimiter. The tuple contains: the left side of the delimiter, the delimiter, the right side of the delimiter info = 'sz-18-180-12345678'result = info.partition (' -') result1 = info.partition ('|') # string, the left side is the original string On the right and in the middle are the empty string print (result) print (result1) output: ('sz',' -','18-180-12345678') ('sz-18-180-12345678,',')

3. Rpartition starts looking from the right.

Returns the tuple according to the specified delimiter, which contains the delimiter on the left and the delimiter on the right.

# a.rpartition () # starts on the right and returns a tuple according to the specified delimiter. The tuple contains: the content on the left side of the delimiter, the delimiter, the content on the right side of the delimiter info = 'sz-18-180-12345678'result = info.rpartition (' -') result1 = info.rpartition ('|') # string, the original string is on the right The left and middle are empty strings print (result) print (result1) output: ('sz-18-180,' -', '12345678') (',', 'sz-18-180-12345678')

4. The join connector splices the elements in the list into strings.

# a.join () # a.join () # use connectors to concatenate the elements in the list into a string names = ['Bob','Tom','Sam'] # loop each element And add the connector names_new1 ='- '.join (names) names_new2 =' .join (names) names_new3 =', '.join (names) print (names_new1) print (names_new2) print (names_new3) between elements: Bob-Tom-SamBob Tom SamBob,Tom,Sam above is all the content of the article "how to use python splicing function".
