How to Read Kmz File in Python

Python File Treatment

In Python, there is no need for importing external library to read and write files. Python provides an inbuilt part for creating, writing, and reading files.

In this file handling in Python tutorial, nosotros will learn:

How to Open a Text File in Python

To open a file, you lot need to use the built-in open up function. The Python file open up office returns a file object that contains methods and attributes to perform various operations for opening files in Python.

Syntax of Python open file function

file_object  = open("filename", "mode")

Hither,

• filename: gives proper name of the file that the file object has opened.
• style: attribute of a file object tells yous which way a file was opened in.

More than details of these modes are explained below

How to Create a Text File in Python

With Write to file Python, you lot tin create a .text files (guru99.txt) by using the lawmaking, nosotros accept demonstrated here:

Step i) Open up the .txt file

f= open up("guru99.txt","due west+")

• We declared the variable "f" to open a file named guru99.txt. Open up takes 2 arguments, the file that we want to open and a cord that represents the kinds of permission or operation we want to practise on the file
• Here, we used "due west" letter in our argument, which indicates Python write to file and it will create file in Python if information technology does non be in library
• Plus sign indicates both read and write for Python create file operation.

Step 2) Enter data into the file

for i in range(10):      f.write("This is line %d\r\n" % (i+1))

• We have a for loop that runs over a range of 10 numbers.
• Using the write function to enter data into the file.
• The output nosotros want to iterate in the file is "this is line number", which we declare with Python write file office and then percent d (displays integer)
• So basically we are putting in the line number that we are writing, so putting it in a carriage return and a new line grapheme

Footstep three) Close the file example

f.shut()

• This volition close the instance of the file guru99.txt stored

Here is the result later code execution for create text file in Python instance:

How to Create a Text File in Python

When you lot click on your text file in our case "guru99.txt" it volition wait something like this

Case of how to create a text file in Python

How to Suspend Text File in Python

Y'all can likewise append/add a new text to the already existing file or a new file.

Step 1)

f=open("guru99.txt", "a+")

One time again if you could see a plus sign in the lawmaking, it indicates that information technology will create a new file if it does non exist. But in our instance we already have the file, so nosotros are not required to create a new file for Python append to file performance.

Footstep 2)

for i in range(2):      f.write("Appended line %d\r\n" % (i+ane))

This will write information into the file in suspend mode.

How to Append Text File in Python

Y'all can come across the output in "guru99.txt" file. The output of the code is that earlier file is appended with new data past Python suspend to file functioning.

How to Read Files in Python

You can read a file in Python by calling .txt file in a "read mode"(r).

Step 1) Open the file in Read mode

f=open("guru99.txt", "r")

Footstep two) Nosotros use the mode function in the code to check that the file is in open mode. If yes, nosotros continue ahead

if f.mode == 'r':

Step iii) Utilise f.read to read file data and store it in variable content for reading files in Python

contents =f.read()

Step 4) Impress contents for Python read text file

Here is the output of the read file Python case:

How to Read Files in Python

How to Read a File line by line in Python

You tin also read your .txt file line by line if your data is too big to read. readlines() code volition segregate your data in piece of cake to read way.

How to Read a File line by line in Python

When yous run the code (f1=f.readlines()) to read file line past line in Python, information technology volition separate each line and present the file in a readable format. In our instance the line is curt and readable, the output will look similar to the read mode. But if there is a complex data file which is not readable, this slice of code could exist useful.

File Modes in Python

Following are the diverse File Modes in Python:

Mode	Clarification
'r'	This is the default mode. It Opens file for reading.
'w'	This Mode Opens file for writing. If file does not exist, information technology creates a new file. If file exists it truncates the file.
'x'	Creates a new file. If file already exists, the functioning fails.
'a'	Open file in append style. If file does not be, it creates a new file.
't'	This is the default mode. It opens in text way.
'b'	This opens in binary way.
'+'	This will open a file for reading and writing (updating)

Here is the complete code for Python print() to File Example

Python two Example

def master():      f= open up("guru99.txt","w+")      #f=open up("guru99.txt","a+")      for i in range(10):          f.write("This is line %d\r\n" % (i+1))      f.close()         #Open the file dorsum and read the contents      #f=open("guru99.txt", "r")      #   if f.mode == 'r':       #     contents =f.read()      #     print contents      #or, readlines reads the individual line into a list      #fl =f.readlines()      #for x in fl:      #print 10 if __name__== "__main__":   principal()

Python 3 Example

Below is another Python print() to File Example:

def main():     f= open("guru99.txt","w+")     #f=open up("guru99.txt","a+")     for i in range(10):          f.write("This is line %d\r\north" % (i+1))     f.shut()     #Open up the file back and read the contents     #f=open("guru99.txt", "r")     #if f.mode == 'r':     #   contents =f.read()     #    print (contents)     #or, readlines reads the individual line into a list     #fl =f.readlines()     #for x in fl:     #impress(x) if __name__== "__main__":   chief()

Summary

• Python allows you to read, write and delete files
• Use the function open("filename","due west+") for Python create text file. The + tells the python interpreter for Python open text file with read and write permissions.
• To append data to an existing file or Python impress to file operation, utilise the command open("Filename", "a")
• Use the Python read from file role to read the Unabridged contents of a file
• Utilise the readlines role to read the content of the file one by one.
