Method 2 – Python Replace Element in List using Python enumerate() Another way of achieving our goal would be to use enumeration with theenumerate()function: forindex, colorinenumerate(favorite_colors):ifcolor =="Gray": favorite_colors[index] ="Beige"print(favorite_colors)Code language:Python(...
We will now print the new string to see the output. print(string2) We get the below output on printing the new string. We can see that a space has been added in place of a newline character. Thus, we can conveniently replace newline characters with space in Python with the above met...
