Question

Consider python please for this problem:

I did a python program to read the first 20 lines from a file and here is the code

holder = 20
lines = 3
file = "123456.pssm"
_file = ".txt"

while 1:
   
    out_file = input("[OUTPUT] - Please enter the name of file: ") + _file

   
    if (not _file):
        print("Filename not specified - Please Try Again\n")
        continue

    break

with open(_file, "a") as e:
    with open(file, "r") as f:
        for num, line in enumerate(f, 1):
           
            if (line < num < holder + 1):
               
                print(line.strip())
                e.write(line.strip() + "\n")

print("Information saved to {}".format(_file))

What i need is change it to make it take the first 20 columns not rows can you help please

here is the file i need to take the 20 coulmns from

Solution :-

Screenshot of the code...

1 holder 20 lines = 3 3 file "123456.pssm 4 _file ".txt" 6 while 1: out-file input (" [OUTPUT] -Please enter the name of file: ") +-file if (not_file): print("Filename not specified - Please Try Again\n") continue 10 break 12 with open(str(out file), "w) as e: 13 14 15 16 17 18 19 20 21 22 print("Information saved to [?".format(out_file)) with open(file, "r) as f: for line in f: k line.strip).split() if len (k) >= 20: print(line.strip)) for i in range(holder): e.write( kli]") e.write("\n")

Code in the text format (Kindly take care of indentation , refer screenshot if needed ... )

holder = 20
lines = 3
file = "123456.pssm"
_file = ".txt"

while 1:
out_file = input("[OUTPUT] - Please enter the name of file: ") + _file
if (not _file):
print("Filename not specified - Please Try Again\n")
continue
break
with open(str(out_file), "w") as e:
with open(file, "r") as f:
for line in f:
k = line.strip().split()
if len(k) >= 20:
print(line.strip())
for i in range(holder):
e.write( k[i] + " ")
e.write("\n")

print("Information saved to {}".format(out_file))
