Removing the first n characters
To remove the first n characters of a string we can use the slice notation [ ] by passing n: as an argument.
n is the number of characters we need to remove the from the beginning of a string.
Here is an example, that removes the first 3 characters from the following string.
str = "good morning"modified = str[3:]print(modified)
Output:
"d morning"
Alternatively, we can also use the lstrip() method by passing the first n characters as an argument to it.
str = "good morning"modified = str.lstrip("goo")print(modified) # "d morning"
Another example of lstrip() method:
name = "pearson"modified = name.lstrip("pear") # removing first 4 charactersprint(modified) # "son"
