Python Slicing operation

Question

Hi  Team ,

a="$2.39"

print(a[1:-1])

Output - 2.3

Now 

import pandas as pd

rest_data = pd.read_table("rest_data.tsv.txt", sep = '\t')

for i in rest_data["item_price"]:

    print(i[1:-1])

Output- 2.39

Question is in slicing operation only.  I have applied the same slicing in both the case but the result varies. Can you explain why?

Answer 1

The difference in the output which you are seeing is because in your data variable "item_price" is having a space character after each price. So the slicing removes only space from the end of the price but in your first example "a" is not having space at the end of it and that's why the difference in the output
