Python - Display the Contents of a Text File in Reverse Order?

We will display the contents of a text file in reverse order. For that, let us first create a text file amit.txt with the following content 

Display the contents of a text file in Reverse Order with Slicing

Example

Let us now read the contents of the above file in reverse order −

# The file to be read
with open("amit.txt", "r") as myfile:
   my_data = myfile.read()

# Reversing the data by passing -1 for [start: end: step]
rev_data = my_data[::-1]

# Displaying the reversed data
print("Reversed data = ",rev_data)

Output

Reversed data = !tisisihT

Display the contents of a text file in Reverse Order by Looping

Example

# Opening the file to read
my_data = open('amit.txt','r')

# reversing the data
for myLine in my_data:
   l = len(myLine)
   rev_data = ''

while(l>=1):
   rev_data = rev_data + myLine[l-1]
   l=l-1
print("Reversed data = ",rev_data) # Displaying the reversed data

Output

Reversed data = !tisisihT
