# Python – Extract Percentages from String

Given a String, extract all the numbers that are percentages.

Input : test_str = ‘geeksforgeeks 20% is 100% way to get 200% success’
Output : [‘20%’, ‘100%’, ‘200%’]
Explanation : 20%, 100% and 200% are percentages present.

Input : test_str = ‘geeksforgeeks is way to get success’
Output : []
Explanation : No percentages present.

Method #1 : Using findall() + regex

In this, we employ appropriate regex having “%” symbol in suffix and use findall() to get all occurrences of such numbers from String.

## Python3

 `# Python3 code to demonstrate working of  ` `# Extract Percentages from String  ` `# Using regex + findall() ` `import` `re ` ` `  `# initializing strings ` `test_str ``=` `'geeksforgeeks is 100 % way to get 200 % success'` ` `  `# printing original string ` `print``(``"The original string is : "` `+` `str``(test_str)) ` ` `  `# getting required result from string  ` `res ``=` `re.findall(``'\d*%'``, test_str) ` ` `  `# printing result  ` `print``(``"The percentages : "` `+` `str``(res))  `

Output

```The original string is : geeksforgeeks is 100% way to get 200% success
The percentages : ['100%', '200%']
```

Method #2 : Using re.sub() + split()

In this, we perform split of all words, and then from words that have %,  we remove all non-numeric strings. This can be buggy in cases, we have different ordering of % and numbers in string.

## Python3

 `# Python3 code to demonstrate working of  ` `# Extract Percentages from String  ` `# Using re.sub() + split() ` `import` `re ` ` `  `# initializing strings ` `test_str ``=` `'geeksforgeeks is 100 % way to get 200 % success'` ` `  `# printing original string ` `print``(``"The original string is : "` `+` `str``(test_str)) ` ` `  `# extracting words ` `temp ``=` `test_str.split() ` ` `  `# using  ` `res ``=` `[] ` `for` `sub ``in` `temp: ` `    ``if` `'%'` `in` `sub: ` `         `  `        ``# replace empty string to all non-number chars ` `        ``res.append(re.sub(r``'[^\d, %]'``, '', sub)) ` ` `  ` `  `# printing result  ` `print``(``"The percentages : "` `+` `str``(res))  `

Output

```The original string is : geeksforgeeks is 100% way to get 200% success
The percentages : ['100%', '200%']
```
