python write text files code example
Example 1: python make txt file
file = open("text.txt", "w")
file.write("Your text goes here")
file.close()
'r' open for reading (default)
'w' open for writing, truncating the file first
'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
Example 2: python write to file
file = open(“testfile.txt”,”w”)
file.write(“Hello World”)
file.write(“This is our new text file”)
file.write(“and this is another line.”)
file.write(“Why? Because we can.”)
file.close()
Example 3: python write to file
with open(filename,"w") as f:
f.write('Hello World')
Example 4: reading and writing data in a text file with python
file1 = open("MyFile.txt","a")
file2 = open(r"D:\Text\MyFile2.txt","w+")
file1 = open("MyFile.txt","a")
file1.close()
file1 = open("myfile.txt","w")
L = ["This is Delhi \n","This is Paris \n","This is London \n"]
file1.write("Hello \n")
file1.writelines(L)
file1.close()
file1 = open("myfile.txt","r+")
print "Output of Read function is "
print file1.read()
print
file1.seek(0)
print "Output of Readline function is "
print file1.readline()
print
file1.seek(0)
print "Output of Read(9) function is "
print file1.read(9)
print
file1.seek(0)
print "Output of Readline(9) function is "
print file1.readline(9)
file1.seek(0)
print "Output of Readlines function is "
print file1.readlines()
print
file1.close()
file1 = open("myfile.txt","w")
L = ["This is Delhi \n","This is Paris \n","This is London \n"]
file1.close()
file1 = open("myfile.txt","a")
file1.write("Today \n")
file1.close()
file1 = open("myfile.txt","r")
print "Output of Readlines after appending"
print file1.readlines()
print
file1.close()
file1 = open("myfile.txt","w")
file1.write("Tomorrow \n")
file1.close()
file1 = open("myfile.txt","r")
print "Output of Readlines after writing"
print file1.readlines()
print
file1.close()
Output of Readlines after appending
['This is Delhi \n', 'This is Paris \n', 'This is London \n', 'Today \n']
Output of Readlines after writing
['Tomorrow \n']
