Scenario 4: Write a script that parses an application log file, extracts all "ERROR" entries, and generates a formatted markdown report.

log_file = "app.log"
report_file = "error_report.md"

errors = []

# 1. Read and find errors
with open(log_file, "r") as f:
    for line in f:
        if "ERROR" in line:
            errors.append(line.strip())

# 2. Write Markdown report
with open(report_file, "w") as f:
    f.write("# 📋 DevOps Log Incident Report\n\n")
    f.write(f"**Source Log File:** `{log_file}`  \n")
    f.write(f"**Total Incidents Found:** {len(errors)}  \n\n")
    f.write("## ⚠️ Identified Exceptions:\n")
    if errors:
        for idx, error in enumerate(errors, 1):
            f.write(f"{idx}. `{error}`\n")
    else:
        f.write("*No errors detected in the current log range.*\n")

print(f"Report compiled successfully at {report_file}")
