2 Basics
2.1 Numbers
Python 2.7.9 (default, Mar 1 2015, 12:57:24) >>> a = 3.23 >>> b = 4 >>> c = 52.3E-4 >>> print a, b, c 3.23 4 0.00523
2.2 Strings
#!/usr/bin/python
name1 = 'Jack Tan'
name2 = "Ga Xiao Duo"
name3 = '''This is a multi-line string. first line.
second line'''
if name.startswith('Ja'):
print("Yes, name start with 'Ja'")
if 'a' in name:
print('Yes, name contains the string "a"')
if name.find('ac') != -1:
print('Yes, name contains the string "ac"')
deli = '_*_'
mylist = ['Brazil', 'Russia', 'India', 'China']
print(deli.join(mylist))
Output:
Yes, name start with 'Ja' Yes, name contains the string "a" Yes, name contains the string "ac" Brazil_*_Russia_*_India_*_China
