The goal of this kata is to write a function that takes two inputs: a string and a character. The function will count the number of times that character appears in the string. The count is case insensitive.

For example: 

```python
count_char("fizzbuzz","z") => 4
count_char("Fancy fifth fly aloof","f") => 5
```

The character can be any alphanumeric character. 

Good luck.

Starter code:

def count_char(s, c):
	

Solutions:
def count_char(s,c):
    return s.lower().count(c.lower())

def count_char(strng, c):
    return strng.lower().count(c.lower())

def count_char(s, c):
    return s.upper().count(c.upper())

from collections import Counter

def count_char(s, c):
    return Counter(s.lower())[c.lower()]

def count_char(string, letter):
    s = string.lower()
    l = letter.lower()
    return s.count(l)

def count_char(str, char):
    return str.lower().count(char.lower())

def count_char(text, char):
    return text.lower().count(char.lower())

count_char=lambda s,c:s.lower().count(c.lower())

def count_char(line, c):
    line = line.lower()
    return line.count(c.lower())

def count_char(a,b):
    a=a.lower()
    b=b.lower()
    return a.count(b)
