Python | Ways to remove n characters from start of given string

Given a string and a number ‘n’, the task is to remove a string of length ‘n’ from the start of the string. Let’s a few methods to solve the given task.

Method #1: Using Naive Method

 `# Python3 code to demonstrate  ` `# how to remove 'n' characters from starting ` `# of a string ` ` `  `# Initialising string ` `ini_string1 ``=` `'garg_akshat'` ` `  `# Initialising number of characters to be removed ` `n ``=` `5` ` `  `# Printing initial string ` `print` `(``"Initial String"``, ini_string1) ` ` `  `# Removing n characters from string using  ` `# Naive method ` `res ``=` `'' ` `for` `i ``in` `range``(``0``, ``len``(ini_string1)): ` `    ``if` `i>``=` `n: ` `        ``res ``=` `res ``+` `ini_string1[i] ` `         `  `# Printing resultant string ` `print` `(``"Resultant String"``, res) `

Output:

```Initial String garg_akshat
Resultant String akshat
```

Method #2: Using `replace()`

 `# Python3 code to demonstrate  ` `# how to remove 'n' characters from starting ` `# of a string ` ` `  `# Initialising string ` `ini_string1 ``=` `'garg_akshat'` ` `  `# Initialising number of characters to be removed ` `n ``=` `5` ` `  `# Printing initial string ` `print` `(``"Initial String"``, ini_string1) ` ` `  `# Removing n characters from string using  ` `# replace() function ` `res ``=` `ini_string1.replace(ini_string1[:``5``], '', ``1``) ` `         `  `# Printing resultant string ` `print` `(``"Resultant String"``, res) `

Output:

```Initial String garg_akshat
Resultant String akshat
```

Method #3: String slicing

 `# Python3 code to demonstrate  ` `# how to remove 'n' characters from starting ` `# of a string ` ` `  `# Initialising string ` `ini_string1 ``=` `'gargakshat123'` ` `  `# Initialising number of characters to be removed ` `n ``=` `5` ` `  `# Printing initial string ` `print` `(``"Initial String"``, ini_string1) ` ` `  `# Removing n characters from a string ` `# This argument count length from zero  ` `# So length to be stripped is passed n-1 ` `res ``=` `ini_string1[``4``:] ` `         `  `# Printing resultant string ` `print` `(``"Resultant String"``, res) ` `    `

Output:

```Initial String gargakshat123
Resultant String akshat123
```
