# Python | Ways to format elements of given list

• Last Updated : 01 Mar, 2019

Given a List of float values, the task is to truncate all float values to 2-decimal digit. Let’s see the different methods to do the task.

Method #1 : Using List comprehension

 `# Python code to truncate float``# values to 2-decimal digits.`` ` `# List initialization``Input` `=` `[``100.7689454``, ``17.232999``, ``60.98867``, ``300.83748789``]`` ` `# Using list comprehension``Output ``=` `[``"%.2f"` `%` `elem ``for` `elem ``in` `Input``]`` ` `# Printing output``print``(Output)`
Output:
```['100.77', '17.23', '60.99', '300.84']
```

Method #2 : Using Map

 `# Python code to truncate float ``# values to 2 decimal digits.`` ` `# List initialization``Input` `=` `[``100.7689454``, ``17.232999``, ``60.98867``, ``300.83748789``]`` ` `# Using map``Output ``=` `map``(``lambda` `n: ``"%.2f"` `%` `n, ``Input``)`` ` `# Converting to list``Output ``=` `list``(Output)`` ` `# Print output``print``(Output)`
Output:

```['100.77', '17.23', '60.99', '300.84']
```

Method #3 : Using format

 `# Python code to truncate float``# values to 2 decimal digits.`` ` `# List initialization``Input` `=` `[``100.7689454``, ``17.232999``, ``60.98867``, ``300.83748789``]`` ` `# Using forrmat``Output ``=` `[``'{:.2f}'``.``format``(elem) ``for` `elem ``in` `Input``]`` ` `# Print output``print``(Output)`
Output:
```['100.77', '17.23', '60.99', '300.84']
```

Method #4 : Using Iteration

 `# Python code to truncate float``# values to 2 decimal digits.`` ` `# List initialization``Input` `=` `[``100.7689454``, ``17.232999``, ``60.98867``, ``300.83748789``]`` ` `# Output list initialization``Output ``=` `[]`` ` `# Iterating``for` `elem ``in` `Input``:``    ``Output.append(``"%.2f"` `%` `elem)`` ` `# Printing output``print``(Output)`
Output:
```['100.77', '17.23', '60.99', '300.84']
```
