split string python

spam = "A B C D"
eggs = "E-F-G-H"

# the split() function will return a list
spam_list = spam.split()
# if you give no arguments, it will separate by whitespaces by default
# ["A", "B", "C", "D"]

eggs_list = eggs.split("-", 3)
# you can specify the maximum amount of elements the split() function will output
# ["E", "F", "G"]

.split python

path = "xlsx_files/risk_on/feature/US10Y.csv"
name = path.split("/")
print(name)

#['xlsx_files', 'risk_on', 'feature', 'US10Y.csv']

split string python

string = 'James Smith Bond'
x = string.split(' ') #Splits every ' ' (space) in the string to a list
# x = ['James','Smith','Bond']
print('The name is',x[-1],',',x[0],x[-1])

python split

>>> '1,2,3'.split(',')
['1', '2', '3']
>>> '1,2,3'.split(',', maxsplit=1)
['1', '2,3']
>>> '1,2,,3,'.split(',')
['1', '2', '', '3', '']

split string python

file='/home/folder/subfolder/my_file.txt'
file_name=file.split('/')[-1].split('.')[0]

python split

a='Beautiful_abs,     asd       is    ; better*than
ugly.dat'
import re
re.split('; |.|,|_|	+| +|*|
',a)  
# you can add seperated term inside | | eg if you want to selerte by $ |$| 
output ['Beautiful', 'abs', '', 'asd', 'is', '', 'better', 'than', 'ugly','dat']
# use as below for white spaces only
a.split()
output : ['Beautiful_abs,', 'asd', 'is', ';', 'better*than', 'ugly.dat']

How split() works in Python?

text= 'Love thy neighbor'

# splits at space
print(text.split())

grocery = 'Milk, Chicken, Bread'

# splits at ','
print(grocery.split(', '))

# Splits at ':'
print(grocery.split(':'))

"""
Output

['Love', 'thy', 'neighbor']
['Milk', 'Chicken', 'Bread']
['Milk, Chicken, Bread']
"""

split function python

  s="ab.1e.1e3"
  w = s.split('.1')
  // w is ["ab","e","e3"]
  // use help(str.split) in your python IDE to know split in detail.

str.split() method in python

split:
# we use split method on a str
# to remove whitespaces at begining and end of str use s.strip() first
s="ab.1e.1e3"
w = s.split('.1')
// w is ["ab","e","e3"]
# IMP see below to see how split method actually splits wrt passed substring
print("ap1oo11rv1".split("1"))
// prints ['ap', 'oo', '', 'rv', '']
// use help(str.split) in your python IDE to know split in detail.
// if .split() is called then split is done wrt successive whitespaces. 
ex.1 print("     a   pp   p ".split()) 
//prints ['a', 'pp', 'p']
// .split(' ') is different
ex.2 print("     a   pp   p ".split()) 
//prints ['', '', '', '', '', 'a', '', '', 'pp', '', '', 'p', '']

join:
w=["as","3e","1"]
a='vf'.join(w)
// w neccessarily needs to be a list of strings.
print(a)
//displays string asvf3evf1
# CONCLUSIONS FROM ABOVE:
- both split and join undo the effect of each other 
- we can write directly in 1 line as well:
print("QR".join("ap1oo1rv1".split("1")))
// prints apQRooQRrvQR
