hello;
I need help in append a data in new file. the problem is the new data are
generated in every run.
so at the end I should get all the changes in one file (means for all running)
if I run 2 times so should get couple of data set.
note all outputs in txt file.
ex:
this is the first run data
1.0362 1.015 1.011 0.9948 1.0024 0.9936
0.9129 0.9184 0.9868 0.9682 0.975 0.8953
1.0627 1.0517 1.0306 1.0387 1.0501 1.0485
1.0467 1.0342 1.0389 1.0109 1.0107 1.0066
next run the data changes in the same output file
1.020 1.043 1.111 0.343 1.454 1.999
0.9129 0.9184 0.9868 0.9682 0.975 0.8953
1.0555 1.2222 1.333 1.4444 1.2222 1.2222
1.1111 1.1111 1.1111 1.1111 1.1111 1.1111
the appended file should be
1.0362 1.015 1.011 0.9948 1.0024 0.9936
0.9129 0.9184 0.9868 0.9682 0.975 0.8953
1.0627 1.0517 1.0306 1.0387 1.0501 1.0485
1.0467 1.0342 1.0389 1.0109 1.0107 1.0066
1.020 1.043 1.111 0.343 1.454 1.999
0.9129 0.9184 0.9868 0.9682 0.975 0.8953
1.0555 1.2222 1.333 1.4444 1.2222 1.2222
1.1111 1.1111 1.1111 1.1111 1.1111 1.1111
more run more data will generate.
I tried so many times without any result.
t=open('old data'.txt')
d=open('new data.txt','w')
while True:
line=t.readline()
if len(line) ==0:
break
volt=line.split()
volt=map(float, volt)
for i in range (len(line.split())):
d.write(str(volt[i])+' ')
d.write('\n')
d.close
but this only bring as same as the old file.
also I found some codes from the committee and tried but still not working.
import sys
def check_dup(fd1):
print fd1
fd1.seek(0,0)
list1=[]
while not done:
x = fd1.readline()
if x == "":
break
else:
list1.append(x)
return list1
fname = 'new data.txt'
fd = open(fname,'a+')
print fd
t=open('old data'.txt'
while not done:
while True:
line=t.readline()
if len(line) ==0:
break
volt=line.split()
volt=map(float, volt)
for i in range (len(line.split())):
print str
flag = check_dup(fd)
print flag
fd.seek(0,2)
fd.write(str(volt[i]) + ' ')
fd.write('\n')
break
looking forward for prompt response,
best regards,
