I am getting this error when trying to print the contents of a CSV file in Python.
Traceback (most recent call last):
File "/Users/cassandracampbell/Library/Preferences/PyCharmCE2018.2/scratches/Player.py", line 5, in
with open('player.csv') as csvfile:
FileNotFoundError: [Errno 2] No such file or directory: 'player.csv'
Get the exact file path to the csv, if you are on a windows get the entire folder path and then the name, and then do:
with open(r'C:\users\path\players.csv') as csvfile:
If you're using a windows and the exact path, easiest to put the r before the path like I did because it is a literal which will allow the string to be interpreted and the path to be found.
You must put player.csv to the same location with your script Player.py
Example like your code, both files should be here: /Users/cassandracampbell/Library/Preferences/PyCharmCE2018.2/scratches/
Or you can put the specific directory of player.csv,
Ex:
with open("/Users/cassandracampbell/Library/Preferences/PyCharmCE2018.2/scratches/player.csv") as csvfile:
...
Check that you have the file in question in same directory as your .py file you're working on. If that doesn't work you might want to use the full path to the file:
with open ('/Users/cassandracampbell/Library/Preferences/PyCharmCE2018.2/scratches/player.CSV') as csvfile:
And you should try to check the name of the file too should be case sensitive otherwise, let's say you have Player.csv then don't try to open player.csv all lower case won't work!
Plus I don't know what you're trying to do with your CSV file, just print the raw content? You might like using pandas.

I have a program that asks the user to enter a directory containing n number of .txt files (texts). I want to open and read all the texts files of this directory entered by the user and, after that, put all the texts together in only one file sequentially...with the code below a get a error message below, which does not make sense because the file "Chapter22.txt" is in the Folder. Can anyone help understand what is going on?
Traceback (most recent call last):
File "/Users/nataliaresende/Dropbox/PYTHON/join_files.py", line 27,
in <module>
join_texts()
File "/Users/nataliaresende/Dropbox/PYTHON/join_files.py", line 13,
in join_texts
with open(file) as b:
FileNotFoundError: [Errno 2] No such file or directory: 'Chapter22.txt'
I've tried to loop in the entered directory opening and reading each of the files and appending them to a list. After that, use the ' '. join method to convert the texts appended to the list into a string. Is there an easier way to do that?
import sys
import os
from pathlib import Path
def join_texts():
files_list=[]
files_directory = Path(input('Enter the path of the files: '))
for file in os.listdir(files_directory):
with open(file) as b:
f=b.read()
files_list.append(f)
joined_files=' '.join(files_list)
print(joined_files)
join_texts()
The expected result would be a file containing all the texts from this directory together. Can anyone help me with that?
I need to be able to create a temporary file with a specified file name and write data to it, then zip said file with filename up along with other files:
fd, path = tempfile.mkstemp(".bin", "filename", "~/path/to/working/directory/")
try:
with os.fdopen(fd, "wb") as tmp:
tmp.write(data)
with ZipFile("zip.zip", "w") as zip:
zip.write("filename")
zip.writestr("file2", file2_str)
zip.writestr("file3", file3_str)
# ...
finally:
os.remove(path)
I think I must be misunderstanding how mkstemp works, I get the error at the first line of code here:
FileNotFoundError: [Errno 2] No such file or directory: '~/path/to/working/directory/filenameq5st7dey.bin'
It looks like a bunch of garbage gets added to the file name before the suffix is put on the file. I've tried this without a suffix and I still get garbage at the end of the file name.
Aside from the garbage in the file name, why do I get a file not found error instead of having a temporary file created in my directory with that name (plus garbage)?
You supplied this argument:
"~/path/to/working/directory/"
Perfectly natural, it makes sense why you would supply it. But it is wrong. If you ls . you likely will not find a ~ directory.
What you were hoping for was expansion to ${HOME}, as the Bourne shell does. In python we must call this function:
os.path.expanduser("~/path/to/working/directory/")
Print the result it returns and you'll see why it's essential.
Some folks prefer to have pathlib do the work for them:
from pathlib import Path
Path("~/path/to/working/directory/").expanduser()
at the moment my python projects opens a csv file through a "hard coded" file path.
readFromCsv(filePath='home/vm/user/test.csv')
My Python project are opened via the console like:
python myproject.py config.cfg
and depending on the config file, there are other paths to other csv files
with open(sys.argv[1], 'r') as input_file:
filePath = input_file.readline().rstrip("\n")
Is there a way to parse the file path to a variable that the following function call work?
readFromCsv(filePath)
Thanks a lot!
I went through couple answers on forum already but without any success.
I am using Linux mint, Python 3.6.0 and i am trying to open CSV in Python but then error occurs:
file = open("~/Desktop/xyz/city.csv", "rb")
FileNotFoundError: [Errno 2] No such file or directory: '~/Desktop/xyz/city.csv'
My code:
import csv
file = open("~/Desktop/xyz/city.csv", "rb")
reader =csv.reader(file)
I also tried to move the file to desktop as in some answers i found, instead of path i used "city.csv". Still doesn't work.
Completely new to Linux and just can't find why this isn't working.
Each reply appreciated!
You should'nt use '~' to specify the path of your directory but the full path instead. E.g. :
import csv
file = open("/home/user/Desktop/xyz/city.csv", "rb")
reader =csv.reader(file)
If you need to use the tilde, you should then use os.path.expanduser('~/Desktop/xyz/city.csv'). E. g. :
import csv
file = open(os.path.expanduser("~/Desktop/xyz/city.csv"), "rb")
reader =csv.reader(file)
The reason for that is that the "tilde expansion" is a user interface feature that is not recognized by the file system: http://www.gnu.org/software/bash/manual/bashref.html#Tilde-Expansion
Try using the full file path, something like this:
file = open("/home/[username]/Desktop/xyz/city.csv", "rb")
Usually ~ does not expand properly. I have found that when it is needed, put $HOME environment variable value into a python variable and then use join to attach it as a prefix to the file name relative position. This also allows you to move the file to a different location and create a function that will allow you to redefine the prefix.
I am trying to automate some plotting using python and fortran together.
I am very close to getting it to work, but I'm having problems getting the result from a glob search to feed into my python function.
I have a .py script that says
import glob
run=glob.glob('JUN*.aijE*.nc')
from plot_check import plot_check
plot_check(run)
But I am getting this error
plot_check(run)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "plot_check.py", line 7, in plot_check
ncfile=Dataset(run,'r')
File "netCDF4.pyx", line 1328, in netCDF4.Dataset.__init__ (netCDF4.c:6336)
RuntimeError: No such file or directory
I checked that the glob is doing its job and it is, but I think it's the format of my variable "run" that's screwing me up.
In python:
>>run
>>['JUN3103.aijE01Ccek0kA.nc']
>>type(run)
<type 'list'>
So my glob is finding the file name of the file I want to put into my function, but something isn't quite working when I try to input the variable "run" in to my function "plot_check".
I think it might be something to do with the format of my variable "run", but I'm not quite sure how to fix it.
Any help would be greatly appreciated!
glob.glob returns a list of all matching filenames. If you know there's always going to be exactly one file, you can just grab the first element:
filenames = glob.glob('JUN*.aijE*.nc')
plot_check(filenames[0])
Or, if it might match more than one file, then iterate over the results:
filenames = glob.glob('JUN*.aijE*.nc')
for filename in filenames:
plot_check(filename)
Perhaps Dataset expects to be passed a single string filename, rather than a list with one element?
Try using run[0] instead (though you may want to check to make sure your glob actually matches a file before you do that).
