Split strings in a text file into different text files

I have the following stings in a text file. I saved the file as file1.txt

I want to split the strings into 3 different files (file2, file3 and file4)

file2 will contain only repeated phrases in the string

file3 will contain non-repeated strings but no integer/numbers

file4 will contain only integers/numbers.

I have written the code below. the code works OK for file2, but not for file3 and file4 I need help with how to write the code to work for file3 and file4

file1 = open("file1.txt", "rt")
file2 = open("file2.txt", "wt")
file3 = open("file3.txt", "wt")
file4 = open("file4.txt", "wt")

content = file1.readlines()
repeat = "Happy Easter Holidays"
print("Processing inputs")

for line in content:
    if repeat in line:
        file2.write(line)
    if repeat not in line:
        file3.write(line)
    if line.isdigit():
        file4.write(line)

file2.close()
file3.close()
file4.close()

print("Output complete")

for file 3: if repeat not in line and not any(i.isdigit() for i in line): ... for file 4 if line.isnumeric(): ... — toing_toing
First of all, close file1 too or better use context manager. Don't use readlines() in such cases: file descriptor itself is iterator and you can just write for line in file1. To get the desired output try the following conditions: if repeat in line, elif line.isnumeric(), else. — SUTerliakov
Or the approach by @toing_noing, if you don't want line 900* to be in any of result files (it's not a number, but contains digits) — SUTerliakov
@toing_toing. Thanks for the quick response. It now works for file3, but for file4, the only output i get is 900. I want all the numbers/integers (total of 8 values) to sent to file4 — Vincent Oke
you probably have empty spaces, try using strip(), before isnumeric(), and I agree with @СтаниславТерляков, that approach is more cleaner — toing_toing

While reading the content of the file python adds the newline character at the end every line and hence isnumeric() does not work

file1 = open("file1.txt", "rt")
file2 = open("file2.txt", "wt")
file3 = open("file3.txt", "wt")
file4 = open("file4.txt", "wt")

def remove_newlines(fname):
    flist = open(fname).readlines()
    return [s.rstrip('\n') for s in flist]

content=remove_newlines("file1.txt")
repeat = "Happy Easter Holidays"
print("Processing inputs")

for line in content:
    if repeat in line:
        file2.write(line+"\n")
    elif line.isnumeric():
        file4.write(line+"\n")
    else:
        file3.write(line+"\n")

file2.close()
file3.close()
file4.close()

print("Output complete")

Here i have added a function that removes newline character while reading the content
