行继续符后面的
syntaxerror意外字符

import sqlite3
sqlite_file = 'my_first_db.sqlite'   # NAME OF THE SQL DATABASE FILE
table_name1 = 'my_table_1'  # NAME OF THE TABLE THAT TO BE CREATED.
table_name2 = 'my_table_2'  # NAME OF THE SECOND TABLE THAT TO BE CREATED.
new_filed = 'my_1st_coulmn' # NAME OF THE COULMN
filed_type = 'INTEGER'      # COULMN DATA TYPE
# CONNECTING TO DATA BASE FILE
conn = sqlite3.connect(sqlite_file)
c =  conn.cursor()
# CREATEING NEW SQLITE TABLE WITH 1 COULMN
c.execute('create table {tn} ({nf}) {ft})'\ .format(tn=table_name1,nf=new_filed,ft=filed_type))
# Creating a second table with 1 column and set it as PRIMARY KEY
# note that PRIMARY KEY column must consist of unique values!
c.execute('create table {tn} ({nf}) {ft} primary key)'\.format(tn=table_name2,nf=new_filed,ft=filed_type))
# Committing changes and closing the connection to the database file
conn.commit()
conn.close()

在编写长查询时，

\用于行继续。因此，如果您继续执行代码，则在创建和执行查询时删除\ before .format（）。

  # CREATEING NEW SQLITE TABLE WITH 1 COULMN
    c.execute('create table {tn} ({nf}) {ft})'.format(tn=table_name1,nf=new_filed,ft=filed_type))
