如何在字符串之前和之后提取组中的数据子集

Question

I have a text file. In text file based on specific word it should make the data into two groups like everything before specific word as 1 group and every thing after specific word as another group

text file some thing like this

hello every one 
Is any space here?

CHAIN

every thing of the 

file lies here

Based on CHAIN we separate text file into two groups

group 1
hello every one 
Is any space here?

group 2
every thing of the 

file lies here

Answer 1

You mentioned you have a text file say test.txt .

You code:

with open("test.txt", "r") as f:
    data = f.readlines()

part1, part2 = ("".join(data).split("CHAIN"))
print(part1)
print(part2)

Gives me:

hello every one
Is any space here?




every thing of the

file lies here

Otherwise other solution is also good.

Answer 2

you can try a solution with split ans access each string using index as given below.

a = """
hello every one 
Is any space here?

CHAIN

every thing of the 

file lies here
"""

print(a.split("CHAIN")[0])
print(a.split("CHAIN")[1])

Answer 3

just for completeness (other answers work as well):

if you have a text file

file = open('file.txt', 'r').read()

print(file.split('CHAIN'))

# if you want to remove the new spaces (\n)

print([text.strip() for text in file.split('CHAIN')])
