python with open file as code example
Example 1: open text file in python
f=open("Diabetes.txt",'r')
f.read()
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
Example 3: python with file.open
# Reference https://docs.python.org/3/library/functions.html#open
# Method 1
file = open("welcome.txt", "r") # mode can be r(read) w(write) and others
data = file.read()
file.close()
# Method 2 - automatic close
with open("welcome.txt") as infile:
data = file.read()
