Can python create a text file?
Python File HandlingIn Python, there is no need for importing external library to read and write files. Python provides an inbuilt function for creating, writing, and reading files. Show
To open a file, you need to use the built-in Syntax of Python open file function file_object = open("filename", "mode") Here,
More details of these modes are explained below How to Create a Text File in PythonWith Write to file Python, you can create a .text files (guru99.txt) by using the code, we have demonstrated here: Step 1) Open the .txt file f= open("guru99.txt","w+")
Step 2) Enter data into the file for i in range(10): f.write("This is line %d\r\n" % (i+1))
Step 3) Close the file instance f.close()
Here is the result after code execution for create text file in Python example: How to Create a Text File in Python When you click on your text file in our case “guru99.txt” it will look something like this Example of how to create a text file in Python How to Append Text File in PythonYou can also append/add a new text to the already existing file or a new file. Step 1) f=open("guru99.txt", "a+") Once again if you could see a plus sign in the code, it indicates that it will create a new file if it does not exist. But in our case we already have the file, so we are not required to create a new file for Python append to file operation. Step 2) for i in range(2): f.write("Appended line %d\r\n" % (i+1)) This will write data into the file in append mode. How to Append Text File in Python You can see the output in “guru99.txt” file. The output of the code is that earlier file is appended with new data by Python append to file operation. Example of How to Append Text File in Python How to Read Files in PythonYou 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") Step 2) We use the mode function in the code to check that the file is in open mode. If yes, we proceed ahead if f.mode == 'r': Step 3) Use f.read to read file data and store it in variable content for reading files in Python contents =f.read() Step 4) Print contents for Python read text file Here is the output of the read file Python example: How to Read Files in Python How to Read a File line by line in PythonYou can also read your .txt file line by line if your data is too big to read. readlines() code will segregate your data in easy to read mode. How to Read a File line by line in Python When you run the code (f1=f.readlines()) to read file line by line in Python, it will separate each line and present the file in a readable format. In our case the line is short and readable, the output will look similar to the read mode. But if there is a complex data file which is not readable, this piece of code could be useful. File Modes in PythonFollowing are the various File Modes in Python:
Here is the complete code for Python print() to File Example Python 2 Example def main(): f= open("guru99.txt","w+") #f=open("guru99.txt","a+") for i in range(10): f.write("This is line %d\r\n" % (i+1)) f.close() #Open 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: #print x if __name__== "__main__": main() Python 3 Example Below is another Python print() to File Example: def main(): f= open("guru99.txt","w+") #f=open("guru99.txt","a+") for i in range(10): f.write("This is line %d\r\n" % (i+1)) f.close() #Open 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: #print(x) if __name__== "__main__": main() Summary
