I need my csv out put to use commas instead of semicolons so I can insert it into my sqlite DB

Right now my nmap csv is putting semicolons in the file which I need to change to commas.
nmap scan
import first
import csv
import nmap
csvFilePath = "nmapscan1.csv"
ipAddress = first.ipAddress
port = first.port
#nmap scan using user input varibles
nm = nmap.PortScanner()
nm.scan(ipAddress,port)
csv = nm.csv()
print(csv)
#writing to csv file
with open(csvFilePath, "w") as csvFile:
csvFile.write(csv)
#changes ; to , for database use
with open(r"nmapscan1.csv") as in_file, open(r"nmapscan.csv", 'w') as
out_file:
semicolonin = csv.reader(in_file, delimiter=';')
commaout = csv.writer(out_file, delimiter=',')
for row in semicolonin:
commaout.writerow(row)
error I get in Ubuntu terminal
Traceback (most recent call last):
File "second.py", line 23, in <module>
semicolonin = csv.reader(in_file, delimiter=';')
AttributeError: '_io.TextIOWrapper' object has no attribute 'reader'

Set a different name to csv on csv = nm.csv(). It is overwriting your csv on import csv.
Edited*
This part:
csv_data = nm.csv()
print(csv_data)
#writing to csv file
with open(csvFilePath, "w") as csvFile:
csvFile.write(csv_data)

Iterator should return strings, not list error with csv.reader

This code shows the error in the title.. Help me out plz.I wrote the following code to write to a csv file reading the input from another file but this shows the error.When i change "r" to "rb" then it shows "iterator should return byte" error.

Your code is applying csv.reader on another csv.reader object. Look carefully at your __main__ and csv_reader function to make sure you understand why this is the case.
A better solution is to use with open... with multiple files:
with open(path, 'wt') as f1, open('csv_path', 'r') as f2:
write = csv.writer(f1, delimiter=',')
read = csv.reader(f2, delimiter=',')

Python csv file tokenizing

I am new to Python programming and recently I am trying to read a csv file and then save the data from that csv file to a text file. This is the code I am using
csv_file = open('example.csv', 'r')
txt_file = open('example.txt', 'w')
with open(txt_file, 'w') as my_output_file:
with open(csv_file, 'r') as my_input_file:
[my_output_file.write(" ".join(row)+'\n') for row in csv.reader(my_input_file)]
my_output_file.close()
I am getting this error
File "c:\Users\Desktop\Folder\tokenizing.py", line 41, in <module>
with open(txt_file, 'w') as my_output_file:
TypeError: expected str, bytes or os.PathLike object, not _io.TextIOWrapper
Does anyone knows why is it complaining?

Pass the filenames to the open calls and use a for loop not a list comp and let the with context managers of the file objects take care of closing the files:
csv_file = 'example.csv'
txt_file = 'example.txt'
with open(txt_file, 'w') as my_output_file:
with open(csv_file, 'r') as my_input_file:
for row in csv.reader(my_input_file):
my_output_file.write(" ".join(row)+'\n')

how to make a copy from csv file to edit it

when i'm trying to make a copy from csv file to edit it away of the original
then I apply the effects to the original
import csv
import shutil
from tempfile import NamedTemporaryFile
filename = "data1.csv"
temp_file = NamedTemporaryFile(delete=False)
print(temp_file.name)
with open(filename, "r",encoding='utf8') as csvfile, temp_file:
reader = csv.DictReader(csvfile)
fieldnames = ["id", "name", "email", "sent"]
writer = csv.DictWriter(temp_file, fieldnames=fieldnames)
# writer.writeheader()
for row in reader:
writer.writerow({
"id":row["id"],
"name":row["name"],
"email":row["email"],
"sent":""
})
I get this error :/

TypeError: a bytes-like object is required, not 'str'

The error is the result of your temp_file being opened in binary mode rather than text mode (the default is w+b). Change it to:
temp_file = NamedTemporaryFile(mode='w', encoding='utf8', delete=False)
(the encoding is not strictly necessary, but since you're specifying it on the input, makes sense to specify it on the output).
See https://docs.python.org/3/library/tempfile.html

CSV file to list of lines?

I have a txt file and I want to save each line as a list in a new file with fname as the new file name. But the output is not being saved. What am I missing?
import csv
with open('file.txt', 'rU') as csvfile:
reader = csv.reader(csvfile, delimiter='\t')
i = 1
for line in reader:
fname = line[0] + line[1]
#print fname
with open(fname, 'w') as out:
out.write(line)
i +=1

To do what you want, you need to fix two things, one is to open the output files in "append" mode so their previous contents aren't wiped-out everytime something additional is written to them.
Secondly you need some way to know the raw data from the file for each csv row it reads. This can be difficult when you use an extension like the csv module and don't know the internals (which you shouldn't use anyway).
To work around that in this case, you can pass a custom csvfile argument to the csv.reader that will give you the information needed. Basically a small preprocessor of the data being read. Here's what I mean:
import csv
def pre_reader(file):
"""Generator that remembers last line read."""
for line in file:
pre_reader.lastline = line
yield line
with open('test_gen.csv', 'rU') as csvfile:
reader = csv.reader(pre_reader(csvfile), delimiter='\t')
i = 1
for line in reader:
fname = line[0] + line[1]
#print fname
with open(fname, 'a') as out:
out.write(pre_reader.lastline)
i +=1

Change:
with open(fname, 'w') as out:
out.write(line)
To:
with open(fname, 'a') as out:
out.write(line)
w Opens a file for writing only. Overwrites the file if the file exists. If the file does not exist, creates a new file for writing.
a Opens a file for appending. The file pointer is at the end of the file if the file exists. That is, the file is in the append mode. If the file does not exist, it creates a new file for writing.
Better way:
import csv
with open('file.txt', 'rU') as csvfile, open(fname, 'w') as out:
reader = csv.reader(csvfile, delimiter='\t')
i = 1
for line in reader:
fname = line[0] + line[1]
out.write(line)

You cannot write a list so change penultimate line to **out.write(str(line))**
import csv
with open('file.txt', 'rU') as csvfile:
reader = csv.reader(csvfile, delimiter='\t')
i = 1
for line in reader:
fname = line[0] + line[1]
#print fname
with open(fname, 'w') as out:
------> out.write(str(line))
i +=1
