Read txt file from specific of line to a certain line base on string-CodePudding

I am trying to write some function of data, however, my data is like this:

noms sommets
0000 Abbesses
0001 Alexandre Dumas
0002 Paris
0004 Nice
...
coord sommets
0000 308 536
0001 472 386
0002 193 404

What I want to is to access from nom sommets to 0004 Nice without knowing the number of line but base on the string value of txt

CodePudding user response：

Read text file to list split based on key word sommets

with open('text.txt') as file:
    lines = [line.rstrip() for line in file]

test_loop = []
for item in lines:
    if 'sommets' in item: 
        test_loop.append([item])
    else:  
        test_loop[-1].append(item)
print(test_loop)

which gives list of lists #.

[['noms sommets', '0000 Abbesses', '0001 Alexandre Dumas', '0002 Paris', '0004 Nice', '...'], ['coord sommets', '0000 308 536', '0001 472 386', '0002 193 404']]

If you want to access first set then.

for sublist in test_loop[0]:
    print(sublist)

Gives #

noms sommets
0000 Abbesses
0001 Alexandre Dumas
0002 Paris
0004 Nice
