If you need to read a specific line from a file using Python, then you can use one of the following options:
Option 1 – Using fileobject.readlines()
If you need to read line 10:
with open("file.txt") as f:
data = f.readlines()[10]
print(data)
If you need to read lines 10, to 20:
with open("file.txt") as f:
data = f.readlines()[10:20]
print(data)
Option 2 – Using for in fileobject
lines =[10, 20]
data = []
i = 0
with open("file.txt", "r+") as f:
for line in f:
if i in lines:
data.append(line.strip)
i = i + 1
print(data)
Option 3 – Using linecache module
import linecache
data = linecache.getline('file.txt', 10).strip()
Option 4 – Using enumerate
with open("file.txt") as f:
for i, line in enumerate(f):
pass # process line i
