python how to read data from a file code example

Example 1: python how to make a file to write to

# Basic syntax:
file_object = open("filename", "mode")
file_object.write("Data to be written")
file_object.close() 

# Example usage:
file_object = open("/path/to/my_filename.txt", "w") # w = write, r = read
file_object.write("Line of text to write")
file_object.close()

Example 2: python open file

with open('filename', 'a') as f: # able to append data to file
	f.write(var1) # Were var1 is some variable you have set previously
	f.write('data') 
	f.close() # You can add this but it is not mandatory 

with open('filename', 'r') as f: # able to read data from file ( also is the default mode when opening a file in python)

with open('filename', 'x') as f: # Creates new file, if it already exists it will cause it to fail

with open('filename', 't') as f: # opens the file in text mode (also is defualt)

with open('filename', 'b') as f: # Use if your file will contain binary data
  
with open('filename', 'w') as f: # Open file with ability to write, will also create the file if it does not exist (if it exists will cause it to fail)
  
with open('filename', '+') as f: # Opens file with reading and writing

# You can combine these as you like with the + for reading and writing
