So I have a text file consisting of one column, each column consist two numbers
190..255
337..2799
2801..3733
3734..5020
5234..5530
5683..6459
8238..9191
9306..9893
I would like to discard the very 1st and the very last number, in this case, 190 and 9893. and basically moves the rest of the numbers one spot forward. like this
My desired output
255..337
2799..2801
3733..3734
5020..5234
5530..5683
6459..8238
9191..9306
I hope that makes sense I'm not sure how to approach this
lines = """190..255
337..2799
2801..3733"""
values = [int(v) for line in lines.split() for v in line.split('..')]
# values = [190, 255, 337, 2799, 2801, 3733]
pairs = zip(values[1:-1:2], values[2:-1:2])
# pairs = [(255, 337), (2799, 2801)]
out = '\n'.join('%d..%d' % pair for pair in pairs)
# out = "255..337\n2799..2801"
Try this:
with open(filename, 'r') as f:
lines = f.readlines()
numbers = []
for row in lines:
numbers.extend(row.split('..'))
numbers = numbers[1:len(numbers)-1]
newLines = ['..'.join(numbers[idx:idx+2]) for idx in xrange(0, len(numbers), 2]
with open(filename, 'w') as f:
for line in newLines:
f.write(line)
f.write('\n')
Try this:
Here's an example:
a = """190..255
337..2799
2801..3733
3734..5020
5234..5530
5683..6459
8238..9191
9306..9893"""
a_list = a.replace('..','\n').split()
b_list = a_list[1:-1]
b = ''
for i in range(len(a_list)/2):
b += '..'.join(b_list[2*i:2*i+2]) + '\n'
temp = []
with open('temp.txt') as ofile:
for x in ofile:
temp.append(x.rstrip("\n"))
for x in range(0, len(temp) - 1):
print temp[x].split("..")[1] +".."+ temp[x+1].split("..")[0]
x += 1
Maybe this will help:
def makeColumns(listOfNumbers):
n = int()
while n < len(listOfNumbers):
print(listOfNumbers[n], '..', listOfNumbers[(n+1)])
n += 2
def trim(listOfNumbers):
listOfNumbers.pop(0)
listOfNumbers.pop((len(listOfNumbers) - 1))
listOfNumbers = [190, 255, 337, 2799, 2801, 3733, 3734, 5020, 5234, 5530, 5683, 6459, 8238, 9191, 9306, 9893]
makeColumns(listOfNumbers)
print()
trim(listOfNumbers)
makeColumns(listOfNumbers)
I think this might be useful too. I am reading data from a file name list.
data = open("list","r")
temp = []
value = []
print data
for line in data:
temp = line.split("..")
value.append(temp[0])
value.append(temp[1])
for i in range(1,(len(value)-1),2):
print value[i].strip()+".."+value[i+1]
print value
After reading the data I split and store it in the temporary list.After that, I copy data to the main list value which have all of the data.Then I iterate from the second element to second last element to get the output of interest. strip function is used in order to remove the '\n' character from the value.
You can later write these values to a file Instead of printing out.
