Write a function that checks whether a number is in a given range (Inclusive of high and low)
In [7]:
def ran_check(num,low,high):
#Check if num is between low and high (including low and high)
if num in range(low,high+1):
print " %s is in the range" %str(num)
else :
print "The number is outside the range."
If you only wanted to return a boolean:
In [8]:
def ran_bool(num,low,high):
return num in range(low,high+1)
In [9]:
ran_bool(3,1,10)

Write a Python function that accepts a string and calculate the number of upper case letters and lower case letters.
Sample String : 'Hello Mr. Rogers, how are you this fine Tuesday?'
Expected Output :
No. of Upper case characters : 4
No. of Lower case Characters : 33
If you feel ambitious, explore the Collections module to solve this problem!
In [11]:
def up_low(s):
d={"upper":0, "lower":0}
for c in s:
if c.isupper():
d["upper"]+=1
elif c.islower():
d["lower"]+=1
else:
pass
print "Original String : ", s
print "No. of Upper case characters : ", d["upper"]
print "No. of Lower case Characters : ", d["lower"]
In [12]:
s = 'Hello Mr. Rogers, how are you this fine Tuesday?'
up_low(s)
Write a Python function that takes a list and returns a new list with unique elements of the first list.
Sample List : [1,1,1,1,2,2,3,3,3,3,4,5]
Unique List : [1, 2, 3, 4, 5]
In [13]:
def unique_list(l):
# Also possible to use list(set())
x = []
for a in l:
if a not in x:
x.append(a)
return x
In [14]:
unique_list([1,1,1,1,2,2,3,3,3,3,4,5])

Write a Python function to multiply all the numbers in a list.
Sample List : [1, 2, 3, -4]
Expected Output : -24
In [4]:
def multiply(numbers):
total = 1
for x in numbers:
total *= x
return total
In [7]:
multiply([1,2,3,-4])

Write a Python function that checks whether a passed string is palindrome or not.
Note: A palindrome is word, phrase, or sequence that reads the same backward as forward, e.g., madam or nurses run.
In [5]:
def palindrome(s):
s = s.replace(' ','') # This replaces all spaces " " with no space ''. (Fixes issues with strings that have spaces)
return s == s[::-1] # Check through slicing
In [7]:
palindrome('nurses run')
Out[7]:
In [8]:
palindrome('abcba')

Hard:
Write a Python function to check whether a string is pangram or not.
Note : Pangrams are words or sentences containing every letter of the alphabet at least once.
For example : "The quick brown fox jumps over the lazy dog"
Hint: Look at the string module
In [21]:
import string
def ispangram(str1, alphabet=string.ascii_lowercase):
alphaset = set(alphabet)
return alphaset <= set(str1.lower())
In [22]:
ispangram("The quick brown fox jumps over the lazy dog")
Out[22]:
In [23]:
string.ascii_lowercase
