I have this script:
f = open("/ggg/darr/file/", "r+")
a = 0
for line in f:
if a ==58:
print (line)
line1 = "google.ca"
f.write(line1)
print line
a = a+1
f.close()
I want to keep my file but only to change what is written on line 58 to "google.ca" then save it using linux: mint-17.2
# Read data from file
with open('yourfile.txt', 'r') as file:
# read all line in the file to data array
data = file.readlines()
# change data on line 58 (array start from 0)
data[57] = 'Data you need to change'
# Write data back
with open('yourfile.txt', 'w') as file:
file.writelines(data)
You need to decide whether you want to write a new file (with print) or change the old file (with r+ mode and f.write). You will probably be happiest if you write a new file.
dataRead = []
f = open("/ggg/darr/file/", "r+")
a = 0
for line in f:
if a == 58:
line = "google.ca"
dataRead.append(line)
a = a+1
f.close()
f2 = open("/some/new/file","w")
for line in dataRead:
f2.write(line)
f2.close()
With the answer of Adisak Anusornsrirung I wrote it like this:
with open('sss.txt','r') as file:
data = file.readlines()
print (data[14])
file.close()
data[14] = "some data here"+"\n"
with open ("sss.txt", 'w') as file:
file.writelines(data)
file.close()
f = open("sss.txt", 'r')
print (f.read())
f.close()
