How to remove letters from python string

To remove the letters in a string, you can use the index method of the string.

For example, we create a string named s

s = 'python'

If we want to take out the letter t, we can

s[2]

The output result is

't'

Remember that the index subscript of a string starts from 0, which means that the index corresponding to the letter p is 0. The string also supports negative indexes

s[-1]

and the output is

'n'

also You can intercept the specified index

s[2:4]

and output it as

'th'
