# I'm a Python beginner, so how do I print out letters by numbers after receiving letters and numbers together?

Asked 2 weeks ago, Updated 2 weeks ago, 2 views

I've been thinking about it for 4 hours, but I don't have a proper answer

If you enter A5B100, you output 5 A and 100 B.

A function that outputs 80 A and 10 B when A80B10 is entered

I want to make it, but there's a lot to consider whether it's a number length or a character to make it a number. What should I do?

Please refer to it.

``````a = 'A5B100'
b = int(a.split('B').split('A'))
c = int(a.split('B'))
``````

I think he probably wanted something like this. There are string functions such as isalpha and isnumerical.

I just roughly planned it out. Please refer to it.

``````>>> def get_str_count_pair(s: str):
s1 = ''
for i, c in enumerate(s):
if c.isalpha():
s1 += c
else:
s = s[i:]
break
print(s1, s)
n1 = ''
for i, c in enumerate(s):
if c.isnumeric():
n1 += c
else:
s = s[i:]
break
s2 = ''
for i, c in enumerate(s):
if c.isalpha():
s2 += c
else:
s = s[i:]
break
print(s2, s)
n2 = ''
for i, c in enumerate(s):
if c.isnumeric():
n2 += c
else:
s = s[i:]
break
return s1 *(int(n1)) + s2*(int(n2))

>>> get_str_count_pair("A5B10")
A 5B10
B 10
'AAAAABBBBBBBBBB'
>>> get_str_count_pair("AX3B7")
AX 3B7
B 7
'AXAXAXBBBBBBB'
