# len() function

The len() function returns the length
of a string expression.

## Syntax

```
len(str.exp)
```

## Parameter(s)

| str.exp | Expression whose length is returned. |
| --- | --- |

## Example(s)

This assignment statement uses
the len() function to delete the last character
of string.

```
customer = "john"
name.length = len(customer)
print name.length
4
string = "test"
string = string[1,len(string)-1]
print string
tes
```
This outputs a `5`.

```
string = ’abcde’
print len(string)
```
This code gets the length of the result of an arithmetic
expression. The result of the arithmetic expression is converted to
an ASCII string when the len() function is invoked.
The output is 2, because 5 times 10 is 50, and the length of 50 is
2 characters.

```
a = 5
x = len(a * 10)
print x
2
```
