'How write python to Read the first two lines from a text file named "file1.txt" Write the two lines read from "file1.txt" to a new file "file2.txt"
Read the first two lines from a text file named "file1.txt" Write the two lines read from "file1.txt" to a new file "file2.txt"
Solution 1:[1]
a_file = open("file1.txt", "r")
number_of_lines = 2
with open("file2.txt", "w") as new_file:
for i in range(number_of_lines):
line = a_file.readline()
new_file.write(line)
a_file.close()
I'm sure there is a neater solution out there somewhere but this will work! Hope it helps you :)
Solution 2:[2]
For 2 lines:
with open("file1.txt", "r") as r:
with open("file2.txt", "w") as w:
w.write(r.readline() + r.readline())
Each time r.readline()
is called, it goes to the next line. So if you wanted to read n
lines; use:
Note that .readline() + r.readline()
is only 2 seperate lines if there is a new line (\n
) at the end of the first line
with open("file1.txt", "r") as r:
with open("file2.txt", "w") as w:
# Change 2 to number of lines to read
for i in range(2):
w.write(r.readline())
Solution 3:[3]
f1=open("file1.txt","r")
f2=open("file2.txt","w")
fcontent=f1.readline()
f2.write(fcontent)
fcontent=f1.readline()
f2.write(fcontent)
f1.close()
f2.close()
Solution 4:[4]
Write a Python program to
- Read the first two lines from a text file named "file1.txt"
- Write the two lines read from "file1.txt" to a new file called "file2.txt"
- Read "file2.txt" and Print the contents
fhandle1 = open("file1.txt","r")
fhandle2 = open("file2.txt","w")
str = fhandle1.readline()
fhandle2.write(str)
str = fhandle1.readline()
fhandle2.write(str)
fhandle1.close()
fhandle2.close()
fhandle3 = open("file2.txt")
print(fhandle3.read())
fhandle3.close()
