write a list to a file in python code example

Example 1: convert python list to text file

# define list of places
places = ['Berlin', 'Cape Town', 'Sydney', 'Moscow']

with open('listfile.txt', 'w') as filehandle:
    for listitem in places:
        filehandle.write('%s\n' % listitem)

Example 2: Python program to write a list to a file

color = ['Red', 'Green', 'White', 'Black', 'Pink', 'Yellow']
with open('file1.txt','w+') as f:
	for i in color:
		f.write('%s\n'%i)

with open('file1.txt') as f:
	print(f.read())
###############
list1=[]
with open('file1.txt','r+') as f:
	lines = f.readlines()
	for line in  lines:
		item = line[:-1]
		list1.append(item)
	print(list1)
#############

with open('file1.txt','r') as f:
	lines=f.read()
	listli=lines.split('\n')
	print(listli)
	# listli=lines.strip()
	# print(listli)

Example 3: how to save python list to file

import json
a = [1,2,3]
with open('test.txt', 'w') as f:
    f.write(json.dumps(a))

#Now read the file back into a Python list object
with open('test.txt', 'r') as f:
    a = json.loads(f.read())

Example 4: python write a list to a file line by line

# attempt #1
f = open("Bills.txt", "w")
f.write("\n".join(map(lambda x: str(x), bill_List)))
f.close()


# attempt #2
# Open a file in write mode
f = open('Bills.txt', 'w')
for item in bill_List:
f.write("%s\n" % item)
# Close opend file
f.close()

# attempt #3

with open('Bills.txt', 'w') as f:
for s in bill_List:
    f.write(s + '\n')

with open('Bills.txt', 'r') as f:
bill_List = [line.rstrip('\n') for line in f]

# attempt #4
with open('Bills.txt', 'w') as out_file:
out_file.write('\n'.join(
    bill_List))

Example 5: save list to file python

with open('your_file.txt', 'w') as f:
    for item in my_list:
        f.write("%s\n" % item)

Example 6: python write list to text file

f = open("a_file.txt", "w")
for item in a_list:
