# Check if the characters are similar in Python

As the title says I tried to make it as an anti-spam measure A function that returns True if it has the specified number of characters Forgive spaghetti source code You may not be able to use it so much w After powering up, edit to make a new one

# code

Take out character by character and add it to the one to compare it and check if it exists

### The one I made first

``````def similer(b,a,m):
al = list(a)
cc = ""
cu = 0
co = 0
cuo = 0
for c in al:
co += 1
for ck in al:
cuo += 1
if cuo-1 < co-1:
continue
cc = cc + ck
cu += 1
if cu == m:
break
if cu == m:
if cc in b:
return True
cc = ""
cuo = 0
cu = 0
return False
#Spaghetti source code w
#It was a hassle
``````

### The one made by another person in the comment section (additional note)

This one is overwhelmingly easy to understand and compact I learned something Thank you

``````def similer(b,a,m):
return any(a[i:i+m] in b for i in range(len(a) - m))
#Take it with a slice and confirm it and return with any
#It will be a great study
``````

# Example of use

`similer (characters to be checked, characters to be checked, length of words to check if they are worn)` Can be used in.

### spam

A spam message that sends a message with random characters that was a chat. `True` is back.

``````b = """Hello. This is Flage Chat

a = """Hello. This is Flage Chat

print(similer(b,a,5))
# True
``````

### Ordinary message

False is back because it's not spam.

``````b = """i-FILTER false positive w"""
a = """Was put in a long time ago"""

print(similer(b,a,5))
# False
``````

# Look if you're trying to use

Note! When using it in a chat app, check it several times or repeatedly. If you send it with a person's name, it will be misjudged as spam. Sometimes short sentences cannot be detected. Let's repeat it by increasing the last argument of the function in order.

### False positive example

If you compare these things, the name of the person tasuren will be True.

``````b = """Did tasuren do it?"""
a = """Because tassuren did hugahuga"""

print(similer(b,a,5))
# True
``````

So When `True` is returned as spam five times in a row when sending a message five times It's spam! It is better to make it feel like letting you know.

It's the end!
