例子 (Example)
以下示例显示了writelines（）方法的用法。
This is 1st line
This is 2nd line
This is 3rd line
This is 4th line
This is 5th line
#!/usr/bin/python'
# Open a file in witre mode
fo = open("foo.txt", "rw+")
print "Name of the file: ", fo.name
# Assuming file has following 5 lines
# This is 1st line
# This is 2nd line
# This is 3rd line
# This is 4th line
# This is 5th line
seq = ["This is 6th line\n", "This is 7th line"]
# Write sequence of lines at the end of the file.
fo.seek(0, 2)
line = fo.writelines( seq )
# Now read complete file from beginning.
fo.seek(0,0)
for index in range(7):
line = fo.next()
print "Line No %d - %s" % (index, line)
# Close opend file
fo.close()
当我们运行上面的程序时，它产生以下结果 -
Name of the file: foo.txt
Line No 0 - This is 1st line
Line No 1 - This is 2nd line
Line No 2 - This is 3rd line
Line No 3 - This is 4th line
Line No 4 - This is 5th line
Line No 5 - This is 6th line
Line No 6 - This is 7th line
