How can i get all the lines after the first in a file python?

Question

i would like to know how i could get all lines after the first in a python file

I've tried with this:

fr = open("numeri.txt", "r")

count = 0
while True:
    line = fr.readline(count)
    if line == "":
        break
    count += 1
    print(line)
fr.close()

Could anyone help me? Thanks

Answer 1

You could add an extra if statement to check if count != 0 Since on the first loop it will be 0.

Answer 2

I don't know if i understood well, but to obtain all the lines skipping the first one you can simple do

lines = []
with open("numeri.txt") as fobj:
   lines = fobj.readlines()[1:] 
count = len(lines)+1 if lines else 0 # If you want to maintain the same counting as in your example

Answer 3

Just read the first line without using it:

with open('numeri.txt') as f:
    f.readline()
    lines = f.readlines()
print(*lines, sep='')

To ignore the first line you can also use next(f) (instead of f.readline() ).

This is also fine:

with open('numeri.txt') as f:
    lines = f.readlines()[1:]
print(*lines, sep='')

Answer 4

count = 0
with open(file, 'r') as file:
    next(file.readline())  # skip the first line
    for count, line in enumerate(file.readlines()): # read remaining lines with count
        if not line:  # If line equals ""  this will be True
            break
        print(count, line)
  
count -= 1 # To ignore last lines count. 

Answer 5

Try using l[1:] . It returns a subset of l that consist in the elements of l except the first position.

with open("numeri.txt", "r") as f:
    content = f.readlines()[1:]
for line in content:
    print(line.strip('\n')) # In order to avoid introduce double \n since print ends with a '\n'

EDIT: Based on @riccardo-bucco ' solution:

with open("numeri.txt", "r") as f:
    content = f.readlines()[1:]
    print(*content, sep='')

Answer 6

To print all but the first line:

with open('numeri.txt', 'r') as f:
    output = ''.join(f.readlines()[1:])
    print(output)

Answer 7

start count at 1 so it skips the first line

...
count = 1
