Python multi_line_reader Examples

Example #1

import common
import itertools

alphabet, n = common.multi_line_reader('LEXF.txt')
alphabet = alphabet.split()

kmers = sorted(list(itertools.product(alphabet, repeat=int(n))))

with open('LEXF_result.txt', 'w') as output_file:
    [print(''.join(elem), file=output_file) for elem in kmers]

Example #2

import common
import numpy

input_lines = common.multi_line_reader('RSTR.txt')
number, gc_cont = int(input_lines[0].split()[0]), float(
    input_lines[0].split()[1])
sequence = input_lines[1]
prob_single_letter = [
    gc_cont / 2 if letter in ['G', 'C'] else (1 - gc_cont) / 2
    for letter in sequence
]
prob_single_sequence = numpy.prod(prob_single_letter)
prob_multiple_sequence = 1 - (1 - prob_single_sequence)**number
print(round(prob_multiple_sequence, 3))

Example #3

File: TREE.py Project: NikitinMikhail/rosalind

import common

#Just using the fact that N(edges) = N(nodes) - 1

lines = common.multi_line_reader('TREE.txt')
nodes_num = int(lines[0])
print(nodes_num - len(lines))

Example #4

import common

input_lines = common.multi_line_reader('SETO.txt')
A, B, complete_set = eval(input_lines[1]), eval(input_lines[2]), set(range(1, int(input_lines[0]) + 1))
print('\n'.join(map(str, [A | B, A & B, A - B, B - A, complete_set - A, complete_set - B])))

Example #5

import common
import numpy as np

strand, gc_cont = common.multi_line_reader('PROB.txt')
gc_cont_list = list(map(float, gc_cont.split()))
prob_list = []
for gc_cont in gc_cont_list:
    prob = [
        gc_cont / 2 if letter in ['G', 'C'] else (1 - gc_cont) / 2
        for letter in strand
    ]
    prob_list.append(str(round(np.log10(np.prod(prob)), 3)))

print(' '.join(prob_list))
