[Python] Print a list of lists as a table in Python

I've a list,

L = [['First', 'Last', 'GPA', 'Major', 'Drops'],
['Jane', 'Doe', '3.5', 'CS', '2'], ['Joe', 'Doe', '2.0', 'CpE', '0'],
['Todd', 'Brown', '3.88', 'CS', '5'],
['Mike', 'Smith', '3.88', 'CS', '5']]


And I've to print it in a table like:

--------------------------------------------------------
| First| Last| GPA| Major| Drops|
--------------------------------------------------------
| Jane| Doe| 3.50| CS| 2|
| Joe| Doe| 2.00| CpE| 0|
| Todd| Brown| 3.88| CS| 5|
| Mike| Smith| 3.88| CS| 5|


My code is so far:

L = [['First', 'Last', 'GPA', 'Major', 'Drops'],
['Jane', 'Doe', '3.5', 'CS', '2'],
['Joe', 'Doe', '2.0', 'CpE', '0'],
['Todd', 'Brown', '3.88', 'CS', '5'],
['Mike', 'Smith', '3.88', 'CS', '5']]
count1 = 1
while count1 < len(L):
L[count1][2] = float(L[count1][2])
L[count1][4] = int(L[count1][4])
count1 += 1
h_line = 56 * '-'
first_line = "|"
print (h_line)
s = " "
w = 10
for i in range(len(L[0])):
str1 = (s*(w - len(L[0])) + "%s|" % L[0])
first_line = first_line + str1
print(first_line)
print(h_line)
a = 1
while a < len(L):
second_line = "|"
for j in range (len(L[a])):
if type(L[a][j]) == str :
str2 = (s*(w - len(L[a][j])) + ("%s|" % L[a][j]))
second_line = second_line + str2
elif type(L[a][j]) == float :
str2 = (s*(w-4) + ("%.2f|" % L[a][j]))
second_line = second_line + str2
elif type(L[a][j]) == float :
str2 = (s*(w-1) + ("%i|" % L[a][j]))
second_line = second_line + str2
print (second_line)
a = a + 1


print (h_line)


But my output looks like:

--------------------------------------------------------
| First| Last| GPA| Major| Drops|
--------------------------------------------------------
| Jane| Doe| 3.50| CS|
| Joe| Doe| 2.00| CpE|
| Todd| Brown| 3.88| CS|
| Mike| Smith| 3.88| CS|
--------------------------------------------------------


I can't figure out what I'm doing wrong.
