Respected Sir / Madam I am using IPython 5.3.0 as an interactive mode through Python 3.6.1: Anaconda 4.4.0 for windows (32-bit). My text file (numbers.txt) was in path the C:\\Users\\user\\Desktop\\numbers.txt. First, as per instruction I initialized the %pylab package and tried to load cat command but it is not working. then I check by typing cat? it shows as object 'cat' not found.
We faced 2 issues :1. cat command is specific to unix (linux). It does not work on windows. But certain commands such as pwd ( print working directory ) works on windows. I have installed Python & IPython on my Windows 7 ( Professional )2. The last question the answer is not correct. The question is "Given a file data.txt with 3 columns of data separated by spaces, read into 3 separate simple sequences. The answer in the video is : x = loadtxt("data.txt", unpack = True, delimiter=":") Answer should be => x, y, z = loadtxt("data.txt", unpack=True, delimiter=":")3. Second Question also the answer is incorrect. We should be using 3 variables on the LHS
i am using windows os, where to store primes.txt file so that cat can retrieve it ?
hi, i am using windows 10 , the command 'cat primes.txt' is not working please help
Answers of questions 2,3 To separate data into 3 separate sequences, we need 3 variables.But in video ,answer is X=loadtxt("data.txt",unpack=True)Only one variable is used.Is it right.
Sir,Here we are unpacking a file containing 3 columns but storing it in single variable. Is this correct format?
