# Python Program to convert List of Integer to List of String

Given a List of Integers. The task is to convert them to List of Strings.

Examples:

```Input: [1, 12, 15, 21, 131]
Output: ['1', '12', '15', '21', '131']

Input: [0, 1, 11, 15, 58]
Output: ['0', '1', '11', '15', '58']
```

Method 1: Using `map()`

 `# Python code to convert list of  ` `# string into sorted list of integer  ` `   `  `# List initialization  ` `list_int ``=` `[``1``, ``12``, ``15``, ``21``, ``131``] ` `   `  `# mapping  ` `list_string ``=` `map``(``str``, list_int)  ` `   `  `# Printing sorted list of integers  ` `print``(``list``(list_string)) `

Output:

```['1', '12', '15', '21', '131']
```

Example 2: Using list comprehension

 `# Python code to convert list of   ` `# string into sorted list of integer  ` `   `  `# List initialization  ` `list_string ``=` `[``1``, ``12``, ``15``, ``21``, ``131``] ` `   `  `# Using list comprehension  ` `output ``=` `[``str``(x) ``for` `x ``in` `list_string] ` `   `  `# Printing output  ` `print``(output) `

Output:

```['1', '12', '15', '21', '131']
```

Method 3: Using iteration

 `# Python code to convert list of  ` `# string into sorted list of integer  ` `   `  `# List initialization  ` `list_string ``=` `[``1``, ``12``, ``15``, ``21``, ``131``] ` `   `  `   `  `list_int ``=` `[] ` `# using iteration and sorted()  ` `for` `i ``in` `list_string: ` `    ``list_int.append(i) ` `   `  `# printing output  ` `print``(list_int)  `

Output:

```['1', '12', '15', '21', '131']
```
