Python – Length of shortest string in string list
• Last Updated : 17 Dec, 2019

Sometimes, while working with a lot of data, we can have a problem in which we need to extract the minimum length string of all the strings in list. This kind of problem can have application in many domains. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using` min()` + generator expression
The combination of above functionalities can be used to perform this task. In this, we extract all the list lengths using generator expression and return minimum of them using min().

 `# Python3 code to demonstrate working of``# Minimum String length``# using min() + generator expression`` ` `# initialize list ``test_list ``=` `[``'gfg'``, ``'is'``, ``'best'``]`` ` `# printing original list ``print``(``"The original list : "` `+` `str``(test_list))`` ` `# Minimum String length``# using min() + generator expression``res ``=` `min``(``len``(ele) ``for` `ele ``in` `test_list)`` ` `# printing result``print``(``"Length of minimum string is : "` `+` `str``(res))`
Output :
```The original list : ['gfg', 'is', 'best']
Length of minimum string is : 2
```

Method #2 : Using `len() + key argument + min()`
The combination of above functions can be used to perform this task. In this, we extract the minimum length using len() and min(). It is faster than above method as it performs more task built in rather than overhead by generator expression.

 `# Python3 code to demonstrate working of``# Minimum String length``# using len() + key argument + min()`` ` `# initialize list ``test_list ``=` `[``'gfg'``, ``'is'``, ``'best'``]`` ` `# printing original list ``print``(``"The original list : "` `+` `str``(test_list))`` ` `# Minimum String length``# using len() + key argument + min()``res ``=` `len``(``min``(test_list, key ``=` `len``))`` ` `# printing result``print``(``"Length of minimum string is : "` `+` `str``(res))`
Output :
```The original list : ['gfg', 'is', 'best']
Length of minimum string is : 2
```
