Loops and conditionals

For loops

app_ratings = [3.5, 4.5, 4.5, 4.5, 4.5]

for element in app_ratings:
    print(element)

Output
3.5
4.5
4.5
4.5
4.5

Deleting last column from list of lists

index=0
for row in data:
    data[index]=row[:-1]
    index=index+1
for row in data[:3]:
    print(row)

For loops range

years = []
for year in range(min_year, max_year + 1):
    years.append(year)

Nested for loops

for row in data:
    for year_attempt in attempts_per_year:
        year = year_attempt[0]
        if row[0] == year:
            year_attempt[1] += 1
            
print(attempts_per_year)
