line-by-line

I'm currently trying to read lines from a text only file that I have. I found on another stackoverflow( Reading a plain text file in Java ) that you can use Files.lines(..).forEach(..) However I can't actually figure out how to use the for each function to read line by line text, Anyone know where to look for that or how to do so? pardeep131085 Sample content of test.txt Hello Stack Over Flow com Code to read from this text file using lines() and forEach() methods. import java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; import java.util

I would like to read a CSV file from the standard input and process each row as it comes. My CSV outputting code writes rows one by one, but my reader waits the stream to be terminated before iterating the rows. Is this a limitation of csv module? Am I doing something wrong? My reader code: import csv import sys import time reader = csv.reader(sys.stdin) for row in reader: print "Read: (%s) %r" % (time.time(), row) My writer code: import csv import sys import time writer = csv.writer(sys.stdout) for i in range(8): writer.writerow(["R%d" % i, "$" * (i+1)]) sys.stdout.flush() time.sleep(0.5)

I have some dirty work to do, so a Bash script seems to be a good choice. I'm new to Bash, and the experience makes me kind of frustrated. The file mapfiles.txt consists of lines as follow. Each line has four segments separated by a white space. Each segment represents a input parameter to an external program name 'prog'. For example, "cm19_1.png" is the filename , "0001" the index , "121422481" the longitude , and "31035995" the latitude . File: mapfiles.txt cm19_1.png 0001 121422481 31035995 cm19_2.png 0002 121423224 31035995 cm19_3.png 0003 121423967 31035995 … I want to execute similar

I've been using cProfile to profile my code, and it's been working great. I also use gprof2dot.py to visualize the results (makes it a little clearer). However, cProfile (and most other Python profilers I've seen so far) seem to only profile at the function-call level. This causes confusion when certain functions are called from different places - I have no idea if call #1 or call #2 is taking up the majority of the time. This gets even worse when the function in question is six levels deep, called from seven other places. How do I get a line-by-line profiling? Instead of this: function #12,
