How to find max and min from a list

# Pass a list to this function to check for maximum number
def max_check(x):
  max_val = x[0] 
  for check in x: 
    if check > max_val: 
      max_val = check 
  return max_val

# Pass a list to this function to check for minimum number
def min_check(x):
  min_val = x[0] 
  for check in x: 
    if check < min_val: 
      min_val = check 
  return min_val

# Pass a list to this function to check for maximum number
def max_check(x):
  max_val = x[0] 
  for check in x: 
    if check > max_val: 
      max_val = check 
  return max_val
# Pass a list to this function to check for minimum number
def min_check(x):
  min_val = x[0] 
  for check in x: 
    if check < min_val: 
      min_val = check 
  return min_val
#List
my_list = [2, 6, 8, 14, 3, 77, 63]
  #Printing Values
print("Maximum of the list", max_check(my_list))
print("Minimum of the list", min_check(my_list))
